研究目的
Investigating the conditions for printability in selective laser melting (SLM) of austenitic stainless steels, focusing on crack prevention and avoiding the formation of defects such as keyholes, balls, and lack of fusion.
研究成果
The presented methodology accurately predicts the formation of solidification cracking and porosity in SLM of austenitic stainless steels. It offers a comprehensive approach to alloy design and process control, validated by literature data.
研究不足
The study focuses on austenitic stainless steels, particularly 316L, and may not be directly applicable to other materials without further validation. The model assumes simplifications in heat transfer phenomena.
