Why this microstructure form in AlSi10mg made by selective laser melting?

13 September 2024 1 2K Report

I have attached the image of microstructure of AlSi10mg of the laser scanning surface (perpendicular to build direction).

Özgün Ceren Akbay

Dear Mani Thakur ;

Since AlSi10Mg alloy is a eutectic alloy, separation occurs between eutectic silicon and aluminum during solidification. By SLM process, fine lamellar eutectic structure can be obtained, which appears as branched structures in the microstructure.
