摘　　要：作为弥散剂的ＺｒＯ＿２的不同含量对弥散强化铂室温物理、力学性能及高温持久断裂寿命均有影响。实验结果表明，增加ＺｒＯ＿２含量能明显地提高材料的室温抗拉强度和高温持久断裂的寿命，但延展性降低。Influence of different content of ZrO_2 used as dispersant on thephysical and mechanical properties and high temperature endurance of dispersionstrengthened platinum was studied.Experimental results show that with the inerease of ZrO_2 content ultimate tensile strength and high temperature endura-nce of the material obviously was increased,but the ductility was impaired.
