摘要

研究了Al-7Fe-38Sn复合材料经封闭模锻50%后的烧结试样的组织和力学性能。已经确定，样品流的均匀性是由其两端对冲头和模具槽壁的摩擦力值决定的。锻造温度对摩擦力的大小有显著影响。背压的应用不影响材料塑性流动的性质，但可以避免试样的开裂。

Effect of high-temperature forging on the structure and mechanical properties of sintered Al–7Fe–38Sn alloy

The structure and mechanical properties of the sintered Al-7Fe-38Sn composite sample after its processing by forging in a closed die by 50% have been studied. It has been established that the homogeneity of the sample flow is determined by the value of friction forces of its ends against the punches and channel walls of the die. The forging temperature has a significant effect on the value of the friction forces. The application of back pressure does not affect the nature of the plastic flow of the material, but allows one to avoid cracking of the samples.
