【摘要】 对喷射成形超高碳钢的化学成分进行了交叉设计,以确定各元素成分对组织的影响。研究表明:Si并不足以单独阻止喷射成形超高碳钢晶界碳化物的出现,A l对抑制晶界碳化物的生成有很大作用,Cr对晶界碳化物的生成有明显抑制作用,C对超高碳钢晶界碳化物的生成有直接影响。更多还原

【Abstract】 The microstructures of five kinds of spray forming ultra high carbon steel were studied to be aware of the effect of alloy elements on the formation of cementite networks in the edge of the pearlite colonies.The results showed that Al and Cr could prevent cementite networks formed in the edge of grain boundaries.But Si could not prevent that by itself.更多还原
