本文研究了恒定线能量的条件：即激光功率与扫描速度之比保持恒定。在此条件下，研究了速度变化对温度的影响.研究了净能量输入、应变速率和材料流动应力对尺寸、残余应力的综合影响。硬度和显微组织也提出了数值结果进行了实验验证，并用于研究过程瞬态和援助理解的复杂和经常相互冲突的影响的条件。
This paper investigates the condition of constant line energy: that is, the ratio of laser power to scanning velocity is kept constant. Under the condition, the effects of velocity change on temperature. net energy input, strain rate and material flow stress are studied Their collective effects on dimension, residual stress. hardness and microstructure are also presented Numerical results are experimentally validated and used to study process transiency and aid understanding the complex and often conflicting effects of the condition.
