中文摘要: |
金属增材制造中的变形及残余应力对于成形过程及零件性能均会产生一定的影响,两者影响因素众多,在增材制造过程中的演化尚未明确揭示。本文综述了国内外关于金属增材制造变形和残余应力的研究现状,提出“约束力”新概念,为金属增材制造变形和残余应力机理的深入研究提供了新的方法。 |
英文摘要: |
The distortion and residual stress in the metal additive manufacturing have a certain influence on the forming process and the performance of the parts. There are many factors that can influence the distortion and residual stress. The evolutions of the distortion and residual stress in the additive manufacturing process have not been clearly revealed. We review the research status of distortion and residual stress in metal additive manufacturing, and then summarize some laws about them. In addition, we propose the concept of “constraining force”, which can help others more distinctly understand the mechanism of distortion and residual stress in metal additive manufacturing. |
