在此，它涉及使用基于轮廓术的压痕塑性测量（PIP）来获得颗粒金属基复合材料（MMCs）的机械性能信息。这种类型的测试，连同传统的单轴测试，已被应用到四个不同的金属基复合材料（与各种颗粒含量和加工条件）。结果表明，可靠的应力-应变曲线，可以得到使用PIP，虽然过早（预颈）断裂的可能性应注意。密切关注规模效应。由于颗粒的局部空间分布的变化，这些材料的“代表性体积”可能相对较大。这可能导致PIP分布中存在一定量的分散，建议进行多次重复PIP测试以获得宏观特性。然而，它表明，PIP测试可以可靠地检测相对较小的（宏观）各向异性表现出这种类型的锻造材料。
Herein, it is concerned with the use of profilometry‐based indentation plastometry (PIP) to obtain mechanical property information for particulate metal matrix composites (MMCs). This type of test, together with conventional uniaxial testing, has been applied to four different MMCs (produced with various particulate contents and processing conditions). It is shown that reliable stress–strain curves can be obtained using PIP, although the possibility of premature (prenecking) fracture should be noted. Close attention is paid to scale effects. As a consequence of variations in local spatial distributions of particulate, the “representative volume” of these materials can be relatively large. This can lead to a certain amount of scatter in PIP profiles and it is advisable to carry out a number of repeat PIP tests in order to obtain macroscopic properties. Nevertheless, it is shown that PIP testing can reliably detect the relatively minor (macroscopic) anisotropy exhibited by forged materials of this type.
