Abstract

The compositional variation and the microstructural evolution in laser additive manufactured Ti/Ti-6Al-2Zr-1Mo-1V graded structural material were investigated. An anomalous compositional variation and its good correlation with hardness were found. Although, during the forming process, the ratio of Ti-6Al-2Zr-1Mo-1V in feeded powders abruptly changes from 0% to 100%, all the elements exhibit a gradual variation, which is preferred to a graded material because such gradient change can decrease the discontinuity of its microstructures and properties and can remarkably reduce the costs due to the simplified manufacturing process and the rational distribution of materials.
