A new Al-Cu alloy for LPBF developed via ultrasonic atomization

Discover the innovative Al-Cu alloy developed for Laser Powder Bed Fusion (LPBF) through ultrasonic atomization. This article delves into the creation of an Al-Cu alloy with additions of Ti, Cr, and Fe, designed to overcome the hot cracking susceptibility of traditional 2xxx aluminum alloys in LPBF. Learn how the addition of Ti and Cr leads to grain refinement and how near-eutectic Fe addition reduces the solidification temperature range, inhibiting hot cracking. With high nanohardness values, this novel alloy holds promise for advanced manufacturing applications.
