The present paper aims in minimizing defects in laser metal deposition (LMD) of high-strength aluminium alloy 7075. The effects of different TiC nanoparticle contents on the defects (crack and porosity), micros
There is a relative lack of data on the processing parameters suitable for laser metal deposition (LMD) of Al alloys, particularly high strength alloys. The objective of this study is to outline a systematic investigation to define the processing window for LMD of Al alloy 7075. Single linear ...
