Microstructure and properties of Ti/Al lightweight graded material by direct laser deposition

A novel Ti/Al lightweight graded material was fabricated successfully using the direct laser deposition process, with the composition continuously changing from 100 vol.-% Ti6Al4V to 100 vol.-% AlSi10Mg. Microstructures and phase transformations were characterised, and the mechanical properties of the Ti/Al lightweight graded material were investigated. It was found that element concentrations followed a nearly linear relationship along the...
