Effects of W Powder Addition on Microstructure and Properties of YG20C Cemented Carbides AITranslate
Abstract AITranslate
Using two kinds of YG20 C cemented carbides with or without W powder added in the mixing stage as experimental subjects,the effects of W powder on the conventional properties(magnetic force,Rockwell hardness,flexural strength,etc.)and microstructure of the alloy after sintering at different temperatures were studied.The results show that the addition of W powder can promote the grain growth of YG20 C cemented carbide and even lead to the formation of abnormal coarse grains;The amount of solid solution W(or WC)in theγphase of the alloy with W powder decreased from 10.5%at 1 410℃to 10%at 1 480℃,while that without W powder increased from 10.4%to 11.6%;The bending strength of the alloy with W powder decreases sharply with the increase of the sintering temperature,and the decreasing amplitude reaches 580 N/mm^2 from 1 410℃to 1 480℃,while that without W powder is basically stable at 2 500 N/mm^2.
