Structure and properties of solid BK6-OM alloy after electrosintering

In the paper we describe the results of the structure formation and physicomechanical properties of WC-Co hard alloy from he standard especially fine-grained BK6-OM mixture of KZTS (Russia) in electrosintering (ES) process with the use of a constant electric current (I = 3000 A) in a graphite mold i...
