Effect of Particle Size of Tungsten Powder and Sintering Temperature on Properties and Microstructure of Tungsten Alloy with La2O3 AITranslate
Abstract AITranslate
The 92 W alloy with 0.15% La2O3 was prepared by conventional powder metallurgy method, the effects were investigated of coarse and fine tungsten powder with two different particle sizes sintered at 1 490~1 520 ℃ on mechanical properties and microstructure of the prepared high density 92 W alloy.The results show that with the increase of sintering temperature, the tensile strength of the alloy prepared with fine tungsten powder decreases, elongation increases, and impact toughness increases at first and then decreases, while the tensile strength of the alloy prepared with coarse tungsten powder increases at first and then decreases, and the elongation and impact toughness increase.Thus, different sintering temperatures should be adopted for the best comprehensive mechanical properties of tungsten alloy with La2O3 prepared with tungsten powder of different particle sizes.The aggregation and segregation of La2O3 particles in the alloy become more and more obvious with the continuous increase of sintering temperature.The grain size of tungsten alloy prepared with fine tungsten powder is coarser than that of the alloy prepared with coarse tungsten powder at lower sintering temperature, but the result is opposite when sintering is carried out at higher temperature.
