Research advances in powder bed fusion additive manufacturing AlSi10Mg alloy
Powder bed fusion based additive manufacturing of AlSi10Mg alloy has broad application prospects in fields such as automobiles and aerospace due to its advantages of rapid manufacturing,high design flexibility,and low cost.However,defects such as pore and cracks caused by improper process parameters,as well as unique microstructures associated with the melt pool,still affect the performance of printed parts,which is one of the main problems faced by SLM.In the production of AlSi10Mg alloy by EBM,the decrease in strength caused by element evaporation is the main problem,and the technical application is rarely used.This paper summarized and compared the application status and difficulties of selective laser melting(SLM)and electron beam melting(EBM)in AlSi10Mg alloy.The as-built parts printed by the two technologies show obvious difference in microstructure and performance.The solution of the process-structure-property relationship and the development of AM-specific alloy powder systems are common challenges for both,so it is necessary to consider them comprehensively.At the same time,in response to these problems,the future research directions and development trends are discussed.
