Effect of sintering conditions of TiCN-FeAl tools on tool wear in cutting pure iron-based alloys

Abstract

Currently, WC-Co sintered carbides are the most common cutting tool material, and they have excellent hardness and wear resistance. However, W and Co are rare metals, and they have disadvantages such as being expensive due to limited resources and being harmful to the human body. So we have been studying TiCN-FeAl tools, which are rare metal-free sintered tools. In a previous study, we reported that the TiCN-FeAl tool was more wear resistant than commercially available tools but was prone to chipping. In this study, cutting tests were conducted on a pure iron alloy with high ductility, and the effects of sintering conditions of cutting tools on tool wear were investigated through wear and edge observations.
