Influences of RE-Ti Composite Modification on the Structure and Properties of W6Mo5Cr4V2 Alloy
The structural change and properties of W6Mo5Cr4V2 alloy (M2 steel) inoculated by addition of rare earth (RE)-Ti were investigated. The results indicated that the impact toughness and fracture toughness were increased distinctly due to network eutectic carbides elimination, matrix structure refinement, and well-distribution of eutectic carbides. The hardness of modified M2 steel hardly changed. In addition, the high temperature wear resistance was improved.
