Yu最近开发了一种在20至900°C温度范围内通过压痕脆性和低塑性材料来构建应力-应变曲线的试验方法程序。米尔曼，B。Galanov等根据该试验方法，绘制了Si、Ge、SiC、TiB_2和WC/Co硬质合金在上述温度范围内的应力-应变曲线σ -ε，并利用一组具有不同尖端角度γ1的三棱锥压头获得的测量结果提取了弹性点σe、屈服应力σs等力学参数，范围为45至85°C。
A test method procedure for constructing stress-strain curves by indentation of brittle and low plastic materials under temperature ranging from 20 to 900°C was developed recently by Yu. Milman, B. Galanov et al. According to this test method procedure stress-strain curves σ - Є for Si, Ge, SiC, TiB2 and WC/Co hard alloy were constructed in the above temperature region and mechanical parameters such as elastic point, σe, yield stress, σs, etc. were extracted by using the measurement results obtained by a set of trihedral pyramid indenters with different angles at the tip, γ1, ranging from 45 to 85°C.
