Laser Additive Manufacturing of Discontinuously Reinforced Titanium Matrix Composites:Controlling of Microstructure-Property and Aerospace Applications
摘要
Abstract
Due to their high strength,specific strength,modulus,wear resistance,and heat resistance,Discontinuously reinforced titanium matrix composites(DRTMCs)are widely used in extreme environments,including aerospace,defense,and military.Traditional hot working for these composites is inefficient,energy-intensive,complex,and wasteful.Metal laser additive manufacturing(Laser AM)provides a near-net-shape solution for integrated molding of complex components.This paper investigated the Laser AM of DRTMCs reinforced with micro and nano particles,focusing on microstructure control,the formation mechanism of abnormal metallurgical networks,the martensitic effect,and the regulation of reinforcement.It summarized the primary reinforcement mechanisms and elaborated on the key technologies for Laser AM of high-performance DRTMCs,addressing challenges and solutions,prospecting the development trend of AM of metal matrix composites,and potential applications.关键词
