Ti (c, n) - (ti, ta, w) (c, n) - co - alloy for use in a cutting tool for superfinishing

摘要

The present invention relates to a sintered body of a carbonitride alloy with titanium as main component which has improved properties particularly when used as cutting tool material in light finishing cutting operations at high cutting speed. This has been achieved by combining a carbonitride based hard phase of specific chemical composition with an extremely solution hardened Co-based binder phase. IMAGE
