Studying Temperature Effects on Internal Microstresses in Indexable Inserts Made of (Ti,W)C-Co Group Hard Alloys

The article is dedicated to investigating the problem of increasing the efficiency of modular cutting tools with indexable inserts made of hard tool alloys and to describe the most typical types of their damages. The article justifies the relevance of studying the temperature effect of cutting inserts made of (Ti,W)C–Co group hard tool alloys on internal microstresses of the 2nd kind. It contains the data of X-ray studies of samples of hard (TiC 30% WC 66% Co 4%), (TiC 15% WC 79% Co 6%) and (TiC 5% WC 85% Co 10%) alloys using XRD 7000 Shimadzu Maxima automated diffractometer with an add-on heater at temperatures from 20 to 700°C.
