摘要
采用选区激光熔化的方法,对激光扫描速度和激光功率等工艺参数进行优化,研究试样的拉伸性能、致密度及组织结构,分析选区激光熔化工艺参数对力学性能及组织的影响.结果表明:激光扫描速度为800~1 000 mm/s,功率为200~250 W的工艺参数条件可以获得较高力学性能,激光扫描速度和激光功率对力学性能的影响曲线为抛物线型.
The process parameters such as laser scanning speed and laser power are optimized by selective laser melting method.The tensile properties,density and microstructure of the samples are studied.The effects of laser melting process parameters on mechanical properties and microstructure are analyzed.The results show that the laser scanning speed is 800-1000mm/s,when the process parameters power is 200-250W higher mechanical properties can be obtained,and the influence of laser scanning speed and laser power on mechanical properties is parabolic.
