30.Injection molding high proportion of properties and microstructure of the alloy group

Abstract: The higher tungsten content W-Ni-Fe heavy alloy with a high density, strength, excellent performance, suitable for use as kinetic energy penetrators, and radiation shielding materials, and powder injection molding (PIM) in children in the production of complex shape parts with good performance has great potential advantage. Of the 95W-3, 5Ni-1, 5Fe heavy alloy by injection molding, sintering process and discussed the relationship between performance and with the traditional powder metallurgy (PIM) Act made Alloy microstructures were compared with . The results show that the alloy produced by injection molding, higher performance, hardness distribution and microstructure more uniform. 均勻。

31.Tungsten heavy alloy technology

Abstract: Tungsten heavy alloy is a tungsten one of the two most important markets, the modern industrial economy is an integral part. In recent years tungsten heavy alloy technology, has long been a series of high-performance materials, life cycle cost and environmental advantages are significant better than competing high proportion of other materials.
