93W与98W粉末冶金材料摩擦焊接头性能及组织分析

Analyses on microstructure and mechanical properties of friction welded joint of dissimilar powder metallurgy tungsten alloy between 93W and 98W

    摘要
  • 摘要: 为了充分利用93W钨合金和98W钨合金两种粉末冶金材料各自独特性能优势,开发基于这两种钨合金的复合材质是非常必要的.采用自主研制的HSMZ-10型摩擦焊机,利用优选的焊接工艺参数,将93W钨合金和98W钨合金在主轴转速为2000r/min,摩擦变形量为5 mm,摩擦压力为30 MPa,顶锻压力为60 MPa,摩擦顶锻变形速率为20 mm/s的条件下,通过摩擦焊接方法成功地实现了焊接,并对接头和母材进行了金相组织分析和力学性能检测分析.结果表明,接头力学性能良好,无未焊透等焊接缺陷;93W和98W粉末冶金材料之间无成分均一化现象,焊缝的强度大于母材。

     

    Abstract: 93W tungsten alloy and 98W tungsten alloy have their respective advantages in properties, and it is necessary to develop the composite tungsten alloy based on 93W tungsten alloy and 98W tungsten alloy.93W tungsten alloy and 98W alloy were welded by the HSMZ-10 friction welding machine developed by authors and with the optimized welding parameters.The mechanical properties and microstructure of the welded joint were tested and analyzed.The results indicate that the welded joint has good mechanical properties and no welding defects such as incomplete penetration.There is no composition homogenization between 93W tungsten alloy and 98W alloy, and the tensile strength of welded joint is higher than that of the base metals.
