Influences of Sintering Temperature on Mechanical Properties of Nickel-Chromium-Molybdenum Alloy

Ni-Cr-Mo alloys were perforated and sintered at different temperature in vacuum. The influence of sintering temperature on mechanical properties of alloys was investigated by measuring their density, linear shrinkage, tensile strength and hardness. The results show that when sintered at the temperatures that were not higher than 1330 °C , density, linear shrinkage, tensile strength and hardness of the alloys increase slowly with the ascension of sintering temperature; when sintered at 1360 °C , density, linear shrinkage, tensile strength and hardness of the alloys increase quickly; when sintered at 1390 °C , the shape of the samples was eistorted.
