| 中文摘要 | novel cemented hard materials (w0.5al0.5)c-0.5 with varying fe-ni binders were successfully prepared by mechanical alloying and vacuum sintering. it can be observed that all the samples were densified to over 97%. the (fe-ni) alloys have been proved to be good binder phases for sintering (w0.5al0.5)c-0.5. the xrd results show that in all cases, the cemented carbide (w0.5al0.5)c-0.5 is still stable. no peaks belong to n-type phases were detected although the carbon vacancy got the value of 50%. the absence of n-type phases can improve the strength of the bulk samples. it indicated that the replacing w by al can inhibit the formation of n phases. with constant grain size and binder phase content, an optimum combination of hardness and bending strength could be obtained when the bulk samples sintered with a binder 75 at.%fe-25 at.%ni. and the increase of binder content may result in the increase of bending strength and decrease of hardness. it is also found that some (w0.5al0.5)c-0.5-(fe-ni) hard metals had comparable hardness and bending strength to those of wc-co. the results obtained in this study extend the knowledge on (fe-ni) bonded cemented carbides and sintering cemented carbide (w1-xalx)c-y.
