Material Performance Evaluation of Cryogenically Treated Cemented Carbide Inserts

Prashant Jondhale, Vishnu Wakchaure


The materials of cutting tools have a significant influence on the cutting process. These cutting processes have an impact on life of tools used and, thus time of manufacturing and tools cost, accuracy, surface finish, and labour requirement. In order to perform the operation efficiently, the tool should have hardness, compressive and bending strength, and toughness, resistance to heat, and reproducible wear characteristics. The development of new cutting tool materials, pre- treatments and surface treatment has led to a rapid increment in the speed of cutting, and thereby improvement in productionefficiency.
The key challenges are to improve hardness and resistance to wear of the cutting tool. Subzero or cryogenic treatment can be used for enhancing mechanical as well as physical properties of the tool. In this work the cemented carbide insert is subjected to cryogenic treatment in Helium gas for different soaking periods as 10hr, 14hr and 18hr. Further an attempt has been made to quantify and confirm effect of different soaking/holding period along with mechanism responsible for improving the mechanical properties of tools such as hardness, microstructure, and grain size by Vickers hardness test and microstructural investigation. The primary results show that there is a significant increase in hardness and relative decrease in grainsize.

Keywords: material cutting tools,Cryogenic treatments, cemented carbide, wear resistance, hardness.
