Abstract
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 general finishing cutting operations requiring high deformation resistance in combination with relatively high toughness. This has been achieved by combining a carbonitride based hard phase of specific chemical composition with an extremely solution hardened Co-based binder phase.
