TL;DR: In this paper, a design methodology for alloys in AM, using a newly developed Al-Ce alloy as an initial case study, was developed and evaluated using single-line laser melts.

TL;DR: In this paper, the tensile deformation behavior along X and Z directions was evaluated with small-scale in-situ mechanical testing equipped with high-resolution digital image correlation, as well as, multi-scale characterization of builds.

TL;DR: In this paper, electron back scatter diffraction was performed on aluminum-titanium dissimilar metal welds made using a 9-kW ultrasonic additive manufacturing system and the results showed that the aluminum texture at the interface after ultrasonic manufacturing is similar to aluminum texture observed during accumulative roll bonding of aluminum alloys.

TL;DR: In this article, a 9'kW UAM system was used to create joints of Al 1100 and commercially pure titanium, and pushpin delamination tests and shear tests were performed, comparing as-built, heat treated and spark plasma sintering treated samples.

TL;DR: In this paper, the effect of post-weld heat treatments (PWHT) on Al-6061 builds fabricated using the UAM process was explored aiming to improve the mechanical strength of UAM builds.
