Abstract: Over the past decade, metal halide perovskites have been widely employed as the emerging active-materials for technological innovations, and their research has become one of the central goals in the field of energetic materials. Pressure, a new thermodynamic dimension, can tune microstructure, atomic interactions, electronic orbitals, and chemical bonds of materials, thus serves as a potent means to regulate the structures and properties of metal halide perovskites. In addition, pressure paves a novel avenue for probing and understanding the structure-property relationship. Taking the advantage of diamond anvil cell technology and in situ high-pressure characterization techniques, we have comprehensively summarized the pressure-induced evolutions of metal halide perovskites, encompassing structural phase transitions, order-disorder transitions, amorphization, and local structural evolution. We have examined alterations in properties, such as bandgap, photoluminescence, photoelectronic response, and electrical resistance, and other distinctive high-pressure phenomena. This review systematically analyzes the structure-property interplay within these known materials, and offers insights into the design of future novel materials.

年轮式超高压装置自发明以来，已被广泛应用于金刚石和立方氮化硼等超硬材料合成，满足了切割、钻孔、研磨等加工工业领域对超硬材料的需求^[1–2]。年轮式超高压装置主要由年轮式超高压模具和2个对称布置的顶锤组成，其中，年轮式超高压模具由硬质合金压缸和多层高强合金钢支撑环组成^[3–4]。模具的腔体内为合成物质，并采用叶蜡石或MgO作为传压介质进行密封，利用液压机驱动2个对称布置的顶锤对腔体内物质进行挤压来产生超高压力环境，该模具可稳定产生5～10 GPa的压力^[5]。年轮式超高压装置具有压力梯度和温度梯度稳定、样品腔体积大的优点，也被广泛用作科学研究装置，如凝聚态物理、高压化学和地球科学等领域^[6–7]。

年轮式超高压装置的设计工作主要集中在提高腔体的工作尺寸和极限承压能力2个方面。提高这2项指标的优势主要表现在：工业合成金刚石和立方氮化硼时，可显著增加产量，降低能耗，并促进合成物质的稳定生长，使产品品质得到明显提升；可为现代测试技术提供更加稳定的测试环境，更精准地获得测量物质的理化性质数据，并增加数据采集量；可为功能材料的设计合成、高压条件下测试物质的原子结构和新理化性质提供更大腔体、更高压力环境。

在实际设计过程中，腔体的工作尺寸和极限承压能力2项指标是一对矛盾的存在。增大腔体体积，其承压能力会降低；为了获得较高的承压能力，需要减小模具腔体体积。同时，硬质合金压缸工作时，压缸内壁会产生非常高的周向拉应力和剪切应力，从而限制装置的极限承压能力和使用寿命，影响合成物质的产品品质，且增加装置的使用成本^[8–9]。大尺寸的腔体必然对应大尺寸的硬质合金压缸，受硬质合金生产工艺所限，大尺寸硬质合金加工十分困难，并且成本高昂^[10]。因此，年轮式超高压模具腔体大型化受到大尺寸硬质合金加工难和腔体压力难以提高的限制。

为了维持腔体内压力的稳定，需要采用多层支撑环对剖分式压缸进行预紧，导致支撑环的尺寸增加。此外，大尺寸高强钢支撑环的加工也存在诸多困难，如腔体体积为500 cm³的年轮式模具，其支撑环的尺寸可达1.2 m，加工难度极大，特别是热处理质量不均匀容易导致支撑环在装配和工作时断裂^[11]。目前，钢丝或钢带缠绕预紧方法已被应用于大型压机设计领域，但尚未用于合成人造金刚石的超高压模具设计中。

为了提高年轮式模具的极限承压能力、降低支撑环尺寸，进而实现腔体大型化，基于大质量支撑原理和侧向支撑原理，研究人员提出了一种钢丝缠绕离散式超高压模具，即将压缸进行离散，只保留一层支撑环对离散后的压缸进行固定和提前预紧，支撑环外部为钢丝缠绕层，进而实现对离散式压缸的充分预紧。压缸离散后，其周向应力得到有效降低，在外部支撑环与钢丝缠绕层预紧的作用下，压缸离散块相互挤压，提供了更好的大质量和侧向支撑效果，可有效提高模具极限承压能力。同时，硬质合金零件尺寸大大减小，离散后的硬质合金体积仅为整体式压缸的十几分之一，降低了硬质合金的制造难度^[12]。本研究将对缠绕离散式大腔体超高压模具进行设计计算，通过有限元方法对模具应力状态进行分析，并预测其极限承压能力，以期为大腔体、高承压能力的超高压模具设计提供新思路、新方法。

1. 模具的受力分析及计算

模具的受力分析及计算满足以下基本假设：(1) 根据缠绕离散式超高压模具的工作环境，假设钢丝层及各层均处于弹性范围；(2) 钢丝层缠绕紧密，工作内压引起的应力在整个缠绕层厚度上是连续的，且工作压力可通过Lamé公式^[13]计算；(3) 忽略模具端部对应力和变形的影响，作为平面问题处理。

钢丝满足以下基本要求：(1) 钢丝截面均匀，无误差或公差较小；(2) 钢丝组织无缺陷、表面较光滑，且塑性较高；(3) 钢丝韧性较高，工作过程中不会发生断裂。

缠绕离散式大腔体超高压模具受力如所示，其中： ${r_{\rm{s}}}$ 、 ${r_{\rm{a}}}$ 分别为压缸内径、外径， ${r_{\rm{b}}}$ 为支撑环外径， ${r_{\rm{c}}}$ 为钢丝缠绕层外径， $\theta$ 为微元角度。对于离散式压缸，设腔体高度为h，压缸高度为H，有

${p_{\rm{s}}}{r_{\rm{s}}}h = {p_1}{r_{\rm{a}}}H$

(1)

式中： ${p_{\rm{s}}}$ 为工作内压， ${p_1}$ 为压缸与支撑环之间的压力。由式(1)可得， ${p_1} = {{{p_{\rm{s}}}{r_{\rm{s}}}h}}/{{{r_{\rm{a}}}H}}$ 。对于支撑环内部，受离散块传递的内压和钢丝预紧力的作用，在支撑环内 ${r_1}$ 处产生周向应力 ${\sigma _{{t_1}}}$ 和径向应力 ${\sigma _{{r_1}}}$ ，根据微元平衡条件可得

${\sigma _{{t_1}}} - {\sigma _{{r_1}}} = {r_1}\frac{{{\rm{d}}{\sigma _r}_{_1}}}{{{\rm{d}}{r_1}}}$

(2)

支撑环上周向和径向的剪应力为

${\tau _1} = \frac{{{\sigma _t}_{_1} - {\sigma _r}_{_1}}}{2}$

(3)

通过式(2)、式(3)可得支撑环 ${r_{\rm{a}}}$ 和 ${r_{\rm{b}}}$ 处的径向应力 ${\sigma _{{r_{\rm{a}}}}}$ 和 ${\sigma _{{r_{\rm{b}}}}}$ 的关系为

${\sigma _{{r_{\rm{a}}}}} - {\sigma _{{r_{\rm{b}}}}} = 2\int_{{r_{\rm{a}}}}^{{r_{\rm{b}}}} {\frac{{{\tau _1}}}{{{r_1}}}} {\rm{d}}{r_1}$

(4)

通过边界条件可知，支撑环的内壁压力 ${p_1} = - {\sigma _{{r_{\rm{a}}}}}$ ，外壁压力 ${p_2} = - {\sigma _{{r_{\rm{b}}}}}$ ，进一步可得

${p_1} - {p_2} = 2\int_{r_{\rm{a}}}^{r_{\rm{b}}} {\tau _1} {\rm{d}} \ln {r_1}$

(5)

支撑环材料的剪切强度为 $\tau _1^*$ ，对式(5)进行积分可得

${p_1} - {p_2} = 2\tau _1^*\ln \frac{{{r_{\rm{b}}}}}{{{r_{\rm{a}}}}} = 2\tau _1^*\ln K = \tau _1^*\ln {K^2}$

(6)

式中：K为支撑环外径与压缸外径之比。

对于钢丝缠绕层内任意 ${r_2}$ 处，同样取一个微元体，且微元体受力平衡与支撑环微元体受力平衡计算方法一致，有

${\sigma _{{t_{\text{2}}}}} - {\sigma _{{r_{\text{2}}}}} = {r_{\text{2}}}\frac{{{\rm{d}}{\sigma _{{r_{\text{2}}}}}}}{{{\rm{d}}{r_{\text{2}}}}}$

(7)

钢丝以等张力F缠绕的方式进行缠绕预紧，任意半径 ${r_2}$ （ ${r_{\rm{b}}}$ ≤ ${r_2}$ ≤ ${r_{\rm{c}}}$ ）处受到外层钢丝对其预紧产生的径向应力为 ${\sigma _{{r_2}}}$ ，切向应力为 $\sigma' _{{t_2}}$ ，根据Lamé公式有

$\sigma' _{{t_2}} = \frac{{{{{{r_{2}^2}}}}+{r_{\rm{a}}^2}}}{{{{{r_{2}^2}}} - {r_{\rm{a}}^2}}}{\sigma _r}_{_2}$

(8)

而钢丝层内 ${r_2}$ 处微元的切向应力 $\sigma _{{t_2}}^{}$ 应为钢丝张力F与钢丝层内切向应力 $\sigma' _{{t_2}}$ 的叠加，即

$\sigma _{{t_2}}^{} = F - \sigma' _{{t_2}} = F - \frac{{{r_{2}^2}+{r_{\rm{a}}^2}}}{{{r_{2}^2} - {r_{\rm{a}}^2}}}{\sigma _r}_{{{_2}_{}}}$

(9)

联立式(8)和式(9)，得到

$F+\left(1 - \frac{{{r_{2}^2}+{r_{\rm{a}}^2}}}{{{r_{2}^2} - {r_{\rm{a}}^2}}}\right){\sigma _{{r_{2}}}}+{r_2}\frac{{{\rm{d}}{\sigma _{{r_2}}}}}{{{\rm{d}}{r_2}}} = 0$

(10)

由模具的边界条件可知，当 ${r_2} = {r_{\rm{c}}}$ 时， ${\sigma _{{r_2}}} = 0$ ，可得到张力为F的缠绕层半径 ${r_2}$ 处的径向预紧力

${\sigma _{{r_2}}} = F\left(\frac{{{r_{2}^2} - {r_{\rm{a}}^2}}}{{2{r_{2}^2}}}\right)\ln \frac{{{r_{\rm{c}}^2} - {r_{\rm{a}}^2}}}{{{r_{2}^2} - {r_{\rm{a}}^2}}}$

(11)

而支撑环外半径处的径向预紧力为 ${\sigma _{{r_{\rm{b}}}}}$ ，通过式(11)可求得

${r_{\rm{c}}^2} = ({r_{\rm{b}}^2} - {r_{\rm{a}}^2})\exp \frac{{{2r_{\rm{b}}^2}{\sigma _{{r_{\rm{b}}}}}}}{{({r_{\rm{b}}^2} - {r_{\rm{a}}^2})F}}+{r_{\rm{a}}^2}$

(12)

压缸材料为硬质合金YG8，支撑环材料为优质合金钢45CrNiMoVA，钢丝材料为65Mn。考虑到模具的使用工况，压缸、支撑环和钢丝材料的安全系数分别取1.0、1.1和1.1，具体参数如表1所示。本研究中硬质合金压缸腔体半径为10 mm，压缸外半径为60 mm。设定腔体内的均布压力为6 GPa，支撑环外圈径向预紧力为500 MPa，钢丝缠绕张力为700 MPa。计算的模具尺寸如图2所示。

2. 有限元分析

2.1 有限元模型

采用数值模拟获得模具的受力情况并进行对比，综合模具腔体体积，得到模具腔体高度、模具高度等参数的最优值。压缸腔体高为24 mm，模具高为60 mm，压缸锥面角度为45°，压缸腔体的工作压力 ${p_0}$ 为6 GPa，压缸锥面的正压力p(s)和密封介质对锥面的摩擦力f(s)与腔体内的工作压力存在以下关系

$p(s) = {p_0}{{\rm{e}}^{- \tfrac{{ 2\tau s}}{\delta}}}$

(13)

$f(s) = f_0 {p_0}{{\rm{e}}^{-\tfrac{{ 2\tau s}}{\delta}}}$

(14)

式中：τ为传压介质的内摩擦系数， $\delta$ 为压缸锥面上密封介质的厚度，s为密封层任意一点到压缸边缘的距离，f₀为密封介质与压缸之间的摩擦系数。

模具的缠绕层对支撑环和离散式压缸的预紧可通过在支撑环外施加一个等效的预紧外压来模拟，对离散成60°、45°、36°和30°的离散式压缸进行分析。为了缩短计算时间，分别对缠绕离散式超高压模具建立1/12、1/16、1/20和1/24有限元模型。有限元的网格尺寸为1.5 mm，类型为Solid186。采用有限元方法分析模具的受力状态，并预测模具的极限承压能力，同时与整体式压缸进行对比。

2.2 模具应力分析与讨论

2.2.1 模具应力分析

模具工作时，腔体内产生的超高压力会在整体式压缸内壁产生极大的周向拉应力，而硬质合金类脆性材料承受拉应力的能力较低，限制了模具的极限承压能力。整体式压缸经过离散化处理，腔体的工作压力主要沿着模具的径向传递，又由于钢丝缠绕预紧的作用，使得离散式压缸主要受压应力的作用。因此，压缸受力情况得到明显改善。压缸应力随不同离散角度的变化情况如图3所示。

图 3 离散式压缸的等效应力和最大剪切应力分布

Figure 3. Distribution of equivalent stress and maximum shear stress in discrete pressure cylinder

整体式压缸的等效应力和最大切应力分别为7 351.3和4 238.6 MPa。采用最大畸变能理论和最大剪切理论作为判断模具失效的依据，由表1可见，硬质合金压缸在此工况下已经被破坏。压缸内壁与外壁的应力差距较大，这是由于压缸的工作内压在压缸内壁产生了较大的周向应力，而压缸外壁由于受到预紧的压应力作用，导致硬质合金材料没有得到最大化利用。可以看到：离散成60°的压缸已经遭到破坏，而其余离散式压缸可继续提高压力并正常工作；随着压缸离散块离散角度的减小，应力逐渐降低。与整体式压缸相比，离散式压缸的等效应力和最大切应力平均值分别降低了24.1%和24.7%。

基于以上的结果和分析可以推断，离散式压缸可承受更高的压力，而支撑环由于受到外部钢丝缠绕预紧作用，可有效保证模具的安全使用。硬质合金离散块的体积只有整体式压缸的几分之一甚至十几分之一，有效避免了大尺寸硬质合金零件的使用，同时破损的压缸离散块也易于更换。因此，离散式压缸的结构优势可显著降低模具的制造难度和工业应用成本，也能够为超硬材料的生产和科学研究提供大腔体、超高压力的物理环境。

2.2.2 压缸内壁应力分析

硬质合金压缸内壁是承受压力的主要区域，其应力状态对模具的极限承压能力存在重要影响。为方便分析，统计了如图4所示路径上的应力。结果显示，在腔体内部加载压力相等的情况下，与整体式压缸相比，离散式压缸应力明显降低。对于整体式压缸，压缸中部的等效应力和最大剪切应力较大，而端部的应力分别为5 477.1和3 150.0 MPa，腔体中部的等效应力和最大剪切应力比腔体端部分别高1 968和1 411 MPa，压缸中部与端部的应力差值较大，压缸受力不均匀，应力集中明显，限制了压缸的极限承压能力。与整体式压缸相比，离散式压缸内壁应力明显降低，并且这2种应力沿路径的分布较为平缓，应力分布较为均匀。压缸中部的应力随着离散化的进行逐渐降低，但是降低的趋势越来越缓慢，说明不能通过无限增加离散块数量来降低压缸内壁应力。离散式压缸内壁的受力情况得到明显改善，应力沿路径的分布较为平缓，可以推断，离散式压缸可承受更高的压力。

2.2.3 支撑环应力分析

缠绕离散式大腔体超高压模具的支撑环内壁对离散式压缸进行提前预紧，外壁受到钢丝缠绕层的预紧力作用，其应力状态也会对模具的使用产生重要影响。图5给出了支撑环的等效应力和最大剪切应力分布情况。从图5可以看出，沿着径向，等效应力和最大剪切应力均逐渐降低，最大值出现在支撑环内壁的中间部位，且年轮式支撑环内壁在周向上的应力分布均匀。由于离散式压缸在周向上是不连续的，使得其支撑环内壁的等效应力和最大剪切应力在周向上同样不连续，并呈现周期性分布。

图 5 支撑环应力云图

Figure 5. Distribution diagram of supporting ring stress

在同样的加载条件下，随着压缸离散块数量的增加，支撑环的应力逐渐增大，与整体式压缸相比，离散式压缸的支撑环等效应力分别增加了0.8%、11.5%、26.3%和26.7%，最大剪切应力分别增加了0.8%、4.4%、16.4%和17.8%。支撑环应力虽然也在逐渐增大，但是增大的趋势越来越慢。需要特别注意的是，支撑环的应力全部在使用范围内。通过对支撑环内壁应力进行分析可知，随着压缸离散块数量的增加，压缸内壁逐渐出现应力集中趋势，且离散块数量越多，应力集中趋势越明显。这是因为，离散块外壁与支撑环内壁接触面之间在预紧力与工作内压的共同作用下，产生了较大的摩擦力，离散块数量越多，摩擦力在周向上的分布越不均匀，使其表现为应力集中趋势。

2.3 剖分式压缸承压能力预测

利用有限元法对缠绕离散式大腔体超高压模具的极限承压能力进行预测，在有限元模型中，以压缸腔体内的压力为设计变量，范围为4.0～7.5 GPa，每间隔0.1 GPa作为一个设计点，以等效应力和最大剪切应力作为输出参数，并以最大畸变能理论和最大剪切应力理论作为失效判据，当应力达到压缸和支撑环的强度极限时，模具失效。图6给出了预测的模具极限承压能力的变化趋势。依据2个失效判据，整体式压缸的极限承压能力分别为5.31和4.93 GPa。根据最大畸变能理论，60°、45°、36°和30°离散式压缸的极限承压能力分别为6.41、6.55、6.70和6.75 GPa；当采用最大剪切应力理论时，承压能力分别为5.95、6.10、6.15和6.21 GPa。离散式压缸的承压能力明显优于年轮整体式压缸，平均增加了24.3%和23.7%。

图 6 模具极限承压能力预测

从图6还可以看出，压缸离散块数量越多，承压能力越强，但是增加的趋势越来越缓慢。硬质合金的加工成本与加工面数量相关，离散块数量增多会导致制造成本增加。因此，结合压缸的应力分析可知，通过无限增加离散式压缸离散块数量来增加极限承压能力是不可行的。总体来说，离散式压缸无需使用大尺寸硬质合金，可充分保证硬质合金零件的烧结质量；并且压缸遭到破坏后，更换破损的压缸即可重新使用，降低了模具的维护和使用成本。

3. 结　论

提出了一种缠绕离散式大腔体超高压模具结构，即将整体式压缸进行离散化处理，形成组合式压缸结构，通过一层支撑环和钢丝缠绕层进行有效预紧，使压缸具有优异的大质量支撑和侧向支撑效果，其极限承压能力更强，无需使用大尺寸硬质合金，显著降低了模具腔体的大型化难度。分析了模具各层的应力，推导了关键结构参数的计算公式，并采用数值模拟方法获得了模具的应力状态和应力特征并进行分析。与整体式压缸相比，离散式压缸的极限承压能力更强，并且维护和使用成本更低，更易于实现腔体大型化。

对模具极限承压能力与离散块数量关系的研究发现，通过无限提高压缸离散块数量来提高承压能力是不可取的。因此，压缸离散数量的选取原则可以归纳为：当模具压缸尺寸较大时，压缸离散块的数量应该更多，以降低硬质合金制造难度并保障压缸的极限承压能力；当模具的压缸体积较小时，离散块数量应该更少，以降低加工制造费用，同时也能够保证模具的承压能力。
