Effect of rotary swaging deformation on microstructure and mechanical properties of tungsten alloys
为了获得高性能钨合金,对93WNiFe钨合金进行旋锻变形加工,研究旋锻变形量对93WNiFe钨合金力学性能及组织的影响.结果表明,随着变形量的增加,93WNiFe钨合金组织中W晶粒由圆球状逐渐被拉长成长条状,室温抗拉强度随变形量的增加而增加,由982 MPa增加到1622 MPa,断后延伸率随变形量的增加快速降低,由35.5％下降到5.5％.当旋锻变形量小于15％时,随着变形量的增加,93WNiFe合金洛氏硬度快速增加,室温冲击韧性快速降低;当变…查看全部>>
The 93WNiFe alloys were deformed by rotary swaging process to obtain the high-performance tungsten alloys.The effect of rotary swaging deformation on the mechanical properties and microstructure of the 93WNiFe tungsten alloys were studied.The results show that,with the increase of deformation,the W grains in 93WNiFe tungsten alloys are elongated from spheroid to long strip,the tensile strength at room temperature increases from 982 MPa to 1622 MPa,and …查看全部>>
