Abstract

A simple method is proposed whereby meaningful comparisons can be made between the mechanical properties of cermet cutting tool materials. The method is based upon a test originally described by Palmqvist, but includes a procedure for analyzing the data which makes the test much more useful. Thus, it is shown experimentally and analytically that the parameters measured by the Palmqvist test, the crack resistance parameter,W, (which is shown to be linearly related to the critical strain energy release rateG IC) and the hardness,H, are related by the following expression 1/W=AH-B whereA andB are constants. The significance of this result is that it can be employed to quickly classify experimental carbide/binder combinations according to their potential as cutting tool materials havingboth high hardness and good resistance to impact. Thus, a few simple measurements to establish the constantsA andB appropriate to the carbide/binder combination under investigation allow a ready comparison to be made with another system for which the constants have previously been established.
