Microstructural evolution and mechanical properties of maraging steel produced by wire + arc additive manufacture process
TL;DR: In this article, the microstructure and mechanical properties of maraging steel parts were investigated and the micro-hardness and tensile strength of the as deposited alloy reduced from the bottom to the top due to the transient thermal cycling, which resulted in partial aging and non-uniform formation of intermetallic compounds along the building direction.

Dissimilar friction stir welding of Ti–6Al–4V alloy and aluminum alloy employing a modified butt joint configuration: Influences of process variables on the weld interfaces and tensile properties
TL;DR: In this paper, a modified Butt joint configuration was employed into the FSW of Ti-6Al-4V alloy to Al-6Mg alloy with a special pin plunge setup, aiming to obtain a high-quality Ti-to-Al joint, avoid butt flaw or Al melting, and reduce the tool shoulder attrition.
