WC体积分数对WC_p/Fe复合材料组织及压缩性能的影响
|
摘要
为研究WC体积分数对WC_p/Fe复合材料组织、界面及压缩性能的影响,采用粉末烧结法制备了不同WC体积分数的WC_p/Fe复合材料。结果表明:在不同WC体积分数的WC_p/Fe复合材料中,WC颗粒发生了不同程度的溶解,其与基体间均呈冶金结合。随着WC体积分数的增加,WC_p/Fe复合材料的界面等效宽度呈现递减趋势,当WC体积分数为50%时,界面等效宽度最小,为39.8μm;复合材料的压缩强度呈先增大后减小趋势,当WC体积分数达到45%时,压缩强度达到最大值;复合材料的断裂方式由准解理断裂逐渐转向纯解理断裂,当WC体积分数达到50%时,WC_p/Fe复合材料的断裂方式为纯解理断裂。
In order to investigate the effects of WC volume fraction on microstructures,interfaces and compression performances of WC_p/Fe composites,WC_p/Fe composites with different WC volume fractions were prepared by power sintering method.The results show that WC particles have different degrees of dissolution in WC_p/Fe composites with different WC volume fractions,and show metallurgical bond with the matrix.With the increase of WC volume fraction,the interface equivalent widths of WC_p/Fe composites exhibit decreasing trend,and when the WC volume fraction is 50%,the interface equivalent width is the smallest,which is 39.8μm.The compressive strengths of the composites exhibit the trend of increasing firstly and then decreasing,and when WC volume fraction reaches 45%,compression strength reaches the maximum.The fracture modes of the composites transform from quasi-cleavage fracture to pure cleavage fracture,and when WC volume fraction reaches 50%,the fracture mode of WC_p/Fe composite is pure cleavage fracture.
