Metal Carbonitrides

Complex carbides containing boron, occurring frequently in boron-alloyed steels and superalloys, are also named carboborides. Metal borocarbides (see Table 1) are synthesized by powder metallurgical methods or are extracted from a metal matrix. There are pseudoternary or -quaternary borocarbides, such as Mn23(B, C) or (Cr, Mn, Fe)23 (B, C)g (t phases) although boron-carbon substitution in borocarbides is less pronounced than nitrogen-carbon substitution in metal carbonitrides. 

Tables I and 2 give a short overview of the properties important for technical applications of the most well characterized and important binary transition metal carbides and nitrides. Some specific properties which cannot easily be listed in a table, as well as the properties of transition metals carbonitrides) especially those of the most commonly used group ivb carbonitrides) are described in detail later.
