元素的混合粉末是的 Fe-2Cu-2Ni-lMo-0.8C (wt %) 很快,在由火花血浆 sintering 的 6 min 以内的 sintered,和当泉华材料的 densificationdegree 和性能上的 sintering 参数的效果被调查。结果证明当脉搏电流和经常的电流的合适的联合为 sintering 被采用时,当泉华材料的密度和拐弯力量到达了最大值,是 7.61x 10 ~ 3 kg/m~3 和 1540 MPa 分别地。它的相应破裂形态学是描绘的著名计算机生产厂商他混合可锻,内部小粒并且劈开破裂。
Fe-2Cu-2Ni-1Mo-0.8C (wt pct) elemental mixed powders were rapidly sintered within 6 min by spark plasma sintering, and the effects of sintering parameters on the densification degree and performance of the assintered materials were investigated. Results showed that when a proper combination of pulse electric current and constant electric current was employed for sintering, the density and bend strength of the as-sintered material reached the maxima, being 7.61×10^3 kg/m^3 and 1540 MPa, respectively. Its corresponding fracture morphology was characterized as the mix of ductile, intergranular and cleavage fractures.
