扫描方式与预热温度对激光选区熔化制备大尺寸AlSi10Mg合金性能的影响
Effect of Scanning Strategy and Preheating Temperature on Properties of Large-Scale AlSi10Mg Alloy Prepared by Selective Laser Melting
摘 要
采用激光选区熔化技术制备大尺寸AlSi10Mg合金试样，研究了扫描方式（棋盘式扫描与均匀扫描）及基板预热温度（80℃和120℃）对AlSi10Mg合金试样显微组织、密度和力学性能等的影响。结果表明：扫描方式是影响试样相对密度、拉伸性能和冲击性能的主要因素，而预热温度主要影响试样的硬度；预热温度80℃、棋盘式扫描方式下试样的相对密度最大（98.69%），拉伸性能和冲击韧性最好；预热120℃、棋盘式扫描方式下试样的硬度最高（257 HV）。

Abstract
The influence of scanning strategy (chessboard scanning and meander scanning) and substrate preheating temperature (80℃ and 120℃) on microstructure, mechanical properties and density of large-scale AlSi10Mg alloy sample prepared by selective laser melting. The results show that relative density, impact property and tensile property were mainly affected by the scanning strategy, while the preheating temperature determined the hardness of sample. When scanning strategy was chessboard scanning and preheating was at 80℃, the sample had the highest relative density (98.69%), the best tensile property and impact toughness. When scanning strategy was chessboard scanning and preheating was at 120℃, the sample had the highest hardness (257 HV).
