TL;DR: The improved understanding of the factors that control microstructure and properties of TiAl alloys is reviewed together with current work aimed at developing both wrought and cast products in this paper.

TL;DR: In this article, the effects of processing conditions, such as laser power, scan speed, powder feed rate, etc. on the microstructure of the build have been assessed and it has been found that Ti-6Al-4V is very susceptible to the formation of columnar grains during laser deposition.

TL;DR: In this article, a high strength in-process and post-process friendly Al alloy was developed for the selective laser melting (SLM) process, one of the most commonly used additive manufacturing techniques.

TL;DR: In this article, the effects of selective laser melting (SLM) on the microstructure and mechanical properties of A357 aluminium alloys were investigated, where the SLM processing parameters were optimised to achieve maximum density, corresponding to an extremely fine micro structure with very few pores, which translates to differences in mechanical properties compared to conventional cast alloy.

TL;DR: In this paper, the influence of processing parameters on surface roughness in Hastelloy X alloy was studied using an EOSINT M 280 machine and computer simulation was also used to understand thermal profiles at those two surfaces.
