1. introduction. compared to microngrained wcco cemented carbides, ultrafinenanograined cemented carbides exhibit better mechanical properties, such as hardness, fracture toughness, transverse rupture strength, and so on 1,2,3.however, the commonly used method for fabricating ultrafinenanograined cemented carbides mostly required ultrafine or nano size initial.
The nominal chemical compositions of cemented carbides in present work are listed in table 1. 0.5 wt vccrs the grain growth inhibitors were added in the alloys. the mixtures were prepared through ball milling in the anhydrous alcohol for 12h atilling speed of 500 rmin and the balltopowder was 51.
The basic compositions of alloyed grades are 312 wo co, 28 wo tic, 28 wo tac, and 15 wo nbc. the average carbide particle size of these grades is usually between 0.8 and. these straight and alloyed grades pretty much cover most of the cemented carbides.
