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

Representing crack growth in additively manufactured Ti-6Al-4V
TL;DR: In this article, the Hartman-Schijve variant of the NASGRO crack growth equation was applied to data produced for a wide variety of additive manufacturing processes and it was shown that the variability in the various da/dN versus ΔK curves is captured reasonably well by proper changes in the threshold and the effective fracture toughness terms.

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.
