Research progress on laser manufacturing technology for Ni-based superalloys
摘要
Abstract
Ni-based superalloys are critical materials for manufacturing aero-engine turbine blades,and their laser manufacturing technology holds significant application value in damage repair and life extension.This paper systematically reviews the research progress of laser-directed energy deposition technology in the field of Ni-based superalloys manufacturing,focusing on three aspects:microstructural control,mechanical properties analysis,and numerical simulation.The formation mechanisms of typical defects such as pores,cracks,and residual stress during laser processing are analyzed.The regulatory effects of auxiliary fields,such as ultrasonic vibration and pulsed current,on molten pool behavior and microstructure evolution are elaborated.The current research status of tensile properties,wear resistance,and fatigue properties is summarized.Addressing the current challenges,including the unclear relationship among process parameters,microstructural characteristics,and mechanical properties,as well as the unclear mechanisms of multi-field coupling effects,future development directions such as multi-scale characterization and multi-field synergistic regulation are prospected.关键词
