Ti(C,N)-(Ti,Ta,W) (C,N)-Co-legering för seghetskrävande bearbetningstillämpningar |
摘要 |
The present invention relates to a sintered body of a carbonitride alloy with titanium as main component and additionally Ta, W with specific ratio N/(C+N) 0.25-0.50 which has improved properties particularly when used as cutting tool material in cutting operations requiring 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, said Co is contained in at% of 12-16 and hardened mainly by W atoms to obtain a relative magnetic saturation below 0.75 and a coercive force above 11 KA/m. <IMAGE> |
