Critical Review of Laser Additive Manufactured Aluminum Alloys Parts
摘要
Abstract
With the pursuit of material performance and productivity in modern manufacturing industry,laser additive manu-facturing technology has become a research hotspot due to its unique advantages.Due to the excellent performance of alu-minium alloy,laser additive manufacturing of aluminium alloy has been widely used.This paper systematically elucidates the microstructure,corrosion resistance,mechanical properties as well as defect analysis and future development trend of la-ser additively manufactured aluminium alloys.The microstructures of four different types of laser additively manufactured aluminium alloys are explored.It is shown that the non-equilibrium solidification and large temperature gradient in the laser additive manufacturing process lead to a different microstructure from that of the conventional casting process.In terms of corrosion resistance,the laser additively manufactured aluminium alloys showed better corrosion resistance,which is poten-tially advantageous due to the homogeneity of the laser additively manufactured aluminium alloy microstructure and grain refinement.In terms of mechanical properties,the laser additively manufactured aluminium alloys show excellent mechani-cal properties due to their fine grain size,and it is pointed out that the properties of the aluminium alloys can be further im-proved by optimizing the process parameters.Finally,it is pointed out that laser additively manufactured aluminium alloys still face challenges in controlling defects such as porosity and cracks,and future development directions are proposed.关键词
