Abstract

A compact is obtained from a mixed powder of a multi-component system ceramics composed of constitutive elements of at least two metal elements selected from the group consisting of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, and W, N, and optionally C; and Fe, Ni, Co, or an alloy composed of a constitutive element of at least one metal element of Fe, Ni, and Co. A composite material is prepared by sintering the compact.

Claims

exact text as granted — not AI-modified

1 . (Amended) A composite material containing: 
 a multi-component system ceramics composed of N, C, and at least two metal elements selected from the group consisting of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, and W; and    a metal selected from the group consisting of Fe, Ni, Co, and an alloy composed of at least one of Fe, Ni, and Co;    wherein an atomic ratio between C and N satisfies C/N&lt;1.    
     
     
         2 . (Canceled)  
     
     
         3 . (Canceled)  
     
     
         4 . The composite material according to  claim 1 , wherein a ratio of said multi-component system ceramics is 60 to 97% by weight, and a ratio of said metal is 40 to 3% by weight.  
     
     
         5 . (Canceled)
