Evolution of multi-cellular structure on Zr and Er modified Al6Si1Mg alloy fabricated by laser powder bed fusion

Evolution of multi-cellular structure on Zr and Er modified Al6Si1Mg alloy fabricated by laser powder bed fusion

The printability of Al6SiMg0·5Er1·0Zr alloy at various laser power, scan speed, and hatch spacing was investigated. The optimal processing window was determined. The relationship between hatch spacing and lack of fusion (LOF) defects and microstructure is discussed. Hatch spacing significantly affec...
