层间强制冷却对电弧熔丝增材制造钛合金温度场和流场的影响
Influence of Inter-layer Forced Cooling on the Temperature and Flow Fields of Wire Arc Additive Manufactured Titanium Alloys
摘要
Abstract
The wire arc additive manufacturing(WAAM)process is characterized by its low equipment costs and high manufac-turing efficiency,leading to its widespread application in manufacturing fields such as aerospace,shipbuilding,and weaponry.However,the thermal accumulation during the deposition process can adversely affect the efficiency,precision,and quality of the structural formation.The inter-layer forced cooling technology can effectively control the deposition morphology and proper-ties of materials.This study employs numerical simulation methods to explore the temperature and flow fields of molten pools in titanium alloys produced by WAAM under different cooling conditions.The results show that inter-layer forced cooling can effec-tively reduce the preheating temperature of the molten pool,alleviate thermal accumulation during the material deposition pro-cess,and decrease the fluid flow velocity within the molten pool,thereby limiting the flow range of the fluid and impacting the size formation of the molten pool.关键词
