Effects of Raw WC Agglomeration on Microstructure and Properties of WC-7%Co Coarse-grained Cemented Carbide AITranslate
Abstract AITranslate
WC-7%Co coarse-grained cemented carbide was prepared with two groups of ultra-coarse WC powders(Fsss>25μm)of which the particle agglomeration degree is different.The soft agglomerated particles of raw WC powders are dispersed by ball milling,while the hard ones are left in the alloy.The effect of raw WC agglomeration degree on the properties of coarse-grained cemented carbide was studied by metallographic microstructure observation and physical and mechanical properties test of the alloy.The results show that the agglomeration degree of raw WC powders has a great influence on the physical and mechanical properties of the alloy.The coercivity,hardness,average grain size and abrasive wear value of the alloys prepared under the same process conditions are similar.However,the alloy without WC aggregation in the metallographic microstructure performs better in bending strength and impact toughness,and the fracture morphology shows that the alloy has better toughness.
