电弧增材制造超级马氏体不锈钢的研究进展
Research Progress on Wire Arc Additive Manufacturing of Super Martensitic Stainless Steel
摘要
Abstract
Super martensitic stainless steels(SMSS),valued for their high strength,high toughness,and excellent corrosion resistance,have become key materials for major engineering equipment.However,traditional manufacturing techniques struggle to meet the efficient customization demands for large-scale complex components.Wire arc additive manufacturing(WAAM),leveraging its advantages of high deposition rate,low cost,and near-net shaping,offers a novel pathway for fabricating large SMSS components.Nevertheless,the inherent multilayer thermal cycling of WAAM leads to inhomogeneous microstructure evolution and residual stress accumulation,directly affecting the performance uniformity of the components and limiting their widespread application.The research progress in WAAM technology for preparing SMSS is systematically reviewed.It focuses on discussing the microstructure evolution laws in WAAM-processed SMSS and the impact on mechanical properties,while also addressing the influence of shielding gas and inclusions on mechanical performance.Furthermore,the mechanisms by which heat treatment processes affect microstructure and mechanical properties are explored.Finally,future development trends and research directions for WAAM-fabricated SMSS components are outlined.关键词
