Study on Influence of Dewaxing Time on Sintering Temperature of WC-6%Ni Cemented Carbide AITranslate
Abstract AITranslate
WC-6%Ni cemented carbide with different dewaxing time was sintered with 5 MPa pressure at1 420 ℃and 1 470℃for 90 min.And then fracture morphology,microstructure and physical and mechanical properties of the sintered cemented carbide were analyzed.The results show that dewaxing time has relatively great effect on sintering temperature of WC-6%Ni cemented carbide in the two-phase region.With dewaxing time changed,its sintering temperature is changed from 1 420 ℃ to 1 470 ℃.At the sintering temperature of 1 420℃,both hardness and strength of the cemented carbide increase with decreased dewaxing time up to the maximum values of HRA91.5and 3 150N/mm2,respectively.At the sintering temperature of 1 470 ℃,both hardness and strength of the cemented carbide decrease with increased dewaxing time up to the maximum values of HRA91.4and 3 370N/mm^2,respectively.Additionally,the magnetism of the alloy appears with decreased dewaxing time.
