TLDR
In this paper, the relationship between LAM processing parameters and microstructure in as-deposited Ti-6Al-4V was investigated, and the results presented in this paper provide a first look at the relationships between the two parameters.Abstract:
Laser additive manufacturing (LAM) is a manufacturing technique with cost-reduction potential for titanium aerospace components. The mechanical properties of LAM Ti-6Al-4V have been investigated extensively, but little work on microstructure evolution has been performed to date. The results presented here provide a first look at the relationships between LAM processing parameters and microstructure in as-deposited Ti-6Al-4V.read more

The effect of oxygen pickup during selective laser melting on the microstructure and mechanical properties of Ti–6Al–4V lattices
TL;DR: Oxygen levels are artificially raised using repeated melting passes to result in more pickup, leading to significantly reduced ductility and hence reduced strength measured in compression.
Stainless steels fabricated by laser melting : Scaled-down structural hierarchies and microstructural heterogeneities
TL;DR: The clear tendency for shifting from mass production to individual production of net-shape components has been discussed in this paper, with a focus on the use of materials in additive manufacturing, which is revolutionizing the way of production and using of materials.

On the process of transition of the cubic-body-centered modification into the hexagonal-close-packed modification of zirconium
TL;DR: In this paper, the process of transition of the cubic-body-centred modification into the hexagonal-close-packed modification of zirconium can be described by means of a combination of shearing- and dilatation-processes parallel to definite crystallographic directions.
