Abstract (en)
[origin: EP1046724A2] A metal-ceramic material, comprising a heavy metal matrix containing uniformly distributed short ceramic fibers of specified aspect ratio, is new. A metal-ceramic material comprises a matrix of heavy metal (alloy), especially an iron-nickel-molybdenum or cobalt base all containing uniformly distributed short ceramic phase fibers which have a length of 5-15 times their diameter particles and which optionally having a surface layer. An Independent claim is also included for a powder metallurgical process for production of the above metal-ceramic material Preferred Features: The matrix may consist of copper or a copper alloy.
