About
Yongping Lei is a materials scientist and manufacturing engineer whose research has made significant contributions to the field of wire arc additive manufacturing (WAAM), with a particular focus on martensitic stainless steels and process-microstructure-property relationships. Lei's work has been instrumental in advancing the understanding of how arc-based additive manufacturing techniques, especially cold metal transfer (CMT) welding, can be leveraged to fabricate high-performance metallic components. His most influential contributions center on the fabrication and characterization of 2Cr13 martensitic stainless steel components produced via WAAM. His 2017 landmark study, which has garnered over 106 citations, revealed how location-dependent thermal histories within additively manufactured parts directly influence microstructural evolution and mechanical performance — a critical insight for ensuring structural reliability in real-world applications. His follow-up 2018 work (88 citations) further established process stability benchmarks and tensile property standards for WAAM-produced components. More recently, Lei explored robotic CMT deposition of thin-wall structures, demonstrating competitive mechanical properties compared to conventionally manufactured counterparts processed through annealing and quenching-and-tempering treatments. Collectively, his research provides foundational knowledge bridging advanced manufacturing processes with materials science, offering valuable guidance for industries adopting additive manufacturing for structural metal components.
