热处理对电弧增材制造TC4钛合金组织和性能影响的研究进展
Effect of the Heat Treatment on the Microstructures and Properties of TC4 Alloy Fabricated by WAAM
摘要
Abstract
Wire arc additive manufacturing(WAAM)of TC4 titanium alloy has the advantages of low cost and high deposition rate compared to traditional manufacturing process,and has broad application prospects.However,the deposition process can cause uneven microstructure and residual stress,resulting in anisotropy of its mechanical properties.Therefore,appropriate heat treatment processes need to be adopted to eliminate adverse effects and further meet the performance requirements.This paper reviews relevant literatures on the effects of heat treatment on the microstructure and properties of TC4 alloy produced by WAAM both domestically and internationally in recent years.It comprehensively analyzes the influence mechanism of heat treatment on the formation and refinement of equiaxed grains in TC4 alloy,and discusses the factors and mechanisms of heat treatment process on the mechanical properties such as strength,ductility,hardness,fatigue,and creep resistance of TC4 alloy.Finally,the research on the regulation of the microstructure and properties of TC4 alloy by WAAM post heat treatment process was prospected.关键词
