Abstract

Abstract

Laser wire-feed metal additive manufacturing technology has a wide application prospect in aerospace, marine engineering and shipbuilding. In this paper, TC4-DT samples were prepared by the laser wire-feed additive manufacturing technology combined with solution strengthening heat treatment method, based on the initial optimized process parameters. The microstructure, defects and room temperature tensile mechanical properties of the samples at as-deposited state and heat-treated state were respectively studied. It is found that the morphology of as-deposited TC4-DT is composed of columnar grains and acicular αʹ martensite. After solution strengthening heat treatment, equiaxed and columnar dual phase structure is formed, and αʹ martensite is decomposed into acicular structure of α+β. The tensile mechanical properties after heat treatment are equivalent to those of forgings.
