IMPACT OF ADDS ON ALSI10MG'S MICROSTRUCTURE AND MECHANICAL CHARACTERISTICS: A PERSPECTIVE ANALYSIS

Abstract

Selective laser melting (SLM) is superior than layer-by-layer melting when it comes to Additive Manufacturing (AM) for generating complex and unique components. This endeavour aims to optimise the SLM process in order to manufacture AlSi10Mg alloy components with a high density. Optical microscopy and scanning electron microscopy (SEM) were used to examine the AM specimens for micro structural difficulties and macro structural concerns, respectively. The impact of layer thickness on microhardness and ultimate tensile strength (UTS), two mechanical parameters of AlSi10Mg alloy components, was also examined. The microstructure of the deposited layer was found to exhibit unique forms and behaviours both at the edge of the melt pool and farther into the layer, according to the analysis. The tensile strength went up from 60 m to 30 m as the layer thickness went down. This is probably because to the improved surface shape, decreased porosity, and ultra-fine cellular dendritic microstructure. Horizontal evaluations revealed a 24% increase in UTS for samples with a 30 m layer thickness compared to samples with a 60 m layer thickness.
