Construction of Stess-Strain Curves for Brittle Materials by Indentation in a Wide Temperature Range

A test method procedure for constructing stress-strain curves by indentation of brittle and low plastic materials under temperature ranging from 20 to 900 r was developed recently by Yu. Milman, B. Galanov et al. According to this test method procedure stress-strain curves a- e for Si, Ge, SiC, TiB2...

Description
Summary:A test method procedure for constructing stress-strain curves by indentation of brittle and low plastic materials under temperature ranging from 20 to 900 r was developed recently by Yu. Milman, B. Galanov et al. According to this test method procedure stress-strain curves a- e for Si, Ge, SiC, TiB2 and WC/Co hard alloy were constructed in the above temperature region and mechanical parameters such as elastic point, (Ye, yield stress, ay, etc. were extracted by using the measurement results obtained by a set of trihedral pyramid indenters with different angles at the tip, ranging from 45 to 85 deg .
