Investigation of the Influencing Factors on Volume Shrinkage,Impact Toughness and Transverse Rupture Strength of Coarse-grained Cemented Carbides AITranslate
Abstract AITranslate
The effects were studied by orthogonal experiments of carbon content, sintering system, cobalt content, ball to raw material ratio, and milling time on volume shrinkage, impact toughness and transverse rupture strength of coarse-grained cemented carbides. The results show that the most important factors af- fecting alloy volume shrinkage are sintering system and milling time,and those affecting impact toughness are sintering system and cobalt content. The most important factor affecting transverse rupture strength is sintering system. By appropriately increasing sintering temperature, milling time and cobalt content, the coarse-grained cemented carbide with better mierostructure and less defects can be obtained, and its relative density,impact toughness and transverse rupture strength are improved.
