摘要
含钨量较高的W Ni Fe密度高合金具有密度高、强度与韧性配合较好等特点 ,适合用作动能穿甲弹及防辐射屏蔽材料 ;而静液挤压技术在脆性材料变形强化方面具有很大的潜在优势。研究了静液挤压 93W 4.9Ni 2 .1Fe合金的性能与显微组织 ,并与传统的旋锻态 93W 4.9Ni 2 .1Fe合金进行了比较。结果表明 ,经静液挤压变形强化的高比重钨合金 ,硬度分布和显微组织更均匀 ;
W Ni Fe alloy with higher content of tungsten has a series of good properties, such as high density, high strength and good ductility. It's applicable to be used as penetrors, armor piercing bullets, and radiation shields. The hydrostatic extrusion technology has a potential advantage in the deformation strengthening to the metals with higher brittleness. The properties and the microstructure of the 93W Ni Fe are studied. Compared with the traditional swaging technology, the distribution of the hardness and the microstructure are uniform, the properties of this kind of alloy deformed by hydrostatic extrusion are higher.
