Effects of powder mixing technique and tungsten powder

2000年6月15日  Tungsten heavy alloys possess a unique combination of high density, ductility, strength and toughness. They are used extensively as kinetic energy penetrators, counterbalance weights and radiation shields. The alloys are produced from W, Ni, Fe and Cu powders by liquid-phase sintering in vacuum and/or in hydrogen atmosphere.

Effects of powder mixing technique and tungsten powder

2000年6月15日  In this study, tensile properties of the 92.5W–5.25Ni–2.25Fe and 90W–7Ni–3Fe heavy alloys were found to be influenced by powder mixing technique and tungsten powder size. For a given tungsten powder grade (mean particle size 10.5 or 3.4 μm), attritor milled alloys exhibited better tensile properties than those of the turbula

Effect of Mixing Modes and Nano Additives on the

2017年7月14日  The mixing of tungsten bulk powder with and without nanoparticles was performed for 1 h at 60 rpm (rotation per minute). Once both the mixing process is completed the effect of mixing on the structure was analyzed by SEM analysis (Tescan Vega 3, Czech Republic). provided a high degree of homogeneity in structure. Hence, this is

UNDERSTANDING HOMOGENEITY OF POWDER

2021年12月14日  In these cases, homogeneity is predominantly due to distributive mixing. However, there are no reported studies on the mixing behavior of tungsten. Agglomerates of this material are formed during the powder production stage and constitute particles that are welded or fused together.
