Influence of Ti Powder Additions on Microstructure and Mechanical Performance of PBF-LB AA6061
Additive manufacturing of high strength 6xxx series aluminium alloys by powder bed fusion - laser beam (PBF-LB) is limited by hot cracking, driven by their wide solidification range and rapid cooling rates. Nanoparticle additions have shown success to mitigate cracking through grain refinement, but their adoption is re...
