摘要
采用温压方法制备了高密度Fe-2Ni-2Cu-1Mo-1C材料,并研究了烧结温度和烧结时间对温压Fe-2Ni-2Cu-1Mo-1C材料烧结密度和抗拉强度的影响。结果表明:常规温压和模壁润滑温压的烧结密度和抗拉强度随烧结温度和时间的变化而变化,模壁润滑温压的烧结密度和抗拉强度均大于常规温压的;温压材料的抗拉强度为烧结温度和烧结时间的函数,常规温压和模壁润滑温压的抗拉强度随烧结温度和时间变化的线性回归方程(R为相关系数)分别为σb=575+211 153 6f(t,T),R=0.972和σb=595+208 688 3f(t,T),R=0.997。
The high density Fe-2Ni-2Cu-1Mo-1C material was fabricated by warm compaction method, and the influence of sintering temperature and sintering time on the density and tensile strength of warm compacted Fe-2Ni-2Cu-1Mo-1C sintered material were studied. The results show that the sintered density and tensile strength of the conventional warm compacted and die wall lubricating warm compacted samples change with the change of sintering temperatures and time. The sintered density and tensile strength of the die wall lubricating warm compacted material are larger than those of conventional warm compacted samples. The tensile strengths of warm compacted ferrous materials are functions of sintering temperatures and time. The regression for conventional warm compaction conditions and die wall lubricating warm compaction conditions are that σb=575＋211 153 6 f（t, T）, R=0.972 and σb=595＋208 6883 f（t, T）, R=0.997, respectively.
