摘　　要：本论文研究了通过粉末冶金热压工艺制备镍铬钼合金的力学性能。结果表明:随着热压温度的提高,力学性能也提高。经过热压的镍铬钼合金材料具有较高的致密度,但是原料中使用的金属钼粉在热压过程中未能被充分固溶。Mechanical properties of the P/M hot-pressed Ni-Cr-Mo alloy were studied. The results show that mechanical properties increased with hot-pressing temperature. The hot pressed alloy has high density But brittle cleavage is observed in the fracture of hot-pressed Ni-Cr-Mo alloy because molybdenum powder used as ingredient is not dissolved completely during hot-pressing.
