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

Methods for producing forged products and other worked products
Dustin M. Bush,Eric V. Roegner,Edward L. Colvin,Larry N. Mueller,Roberto J. Rioja,Brandon Hendrickson Bodily +5 more
TL;DR: In this paper, a method for producing forged products and other worked products is described, in one embodiment, a method comprises using additive manufacturing to produce a metal shaped-preform and, after the using step, forging the metal shaped preform into a final forged product.

Understanding Microstructure Evolution During Additive Manufacturing of Metallic Alloys Using Phase-Field Modeling
TL;DR: In this article, a multi-scale computational framework is proposed to understand the microstructure evolution process during additive manufacturing of metallic alloys and applied to Ti-6Al-4V alloys: (i) macroscopic finite element calculations for temperature distribution and thermal history; (ii) grainscale phase-field model for solidification and grain growth; (iii) sub-grain-scale phase field model for β→α β → α phase transformations.

Influence of Build Direction on the Fatigue Behaviour of Ti6Al4V Alloy Produced by Direct Metal Laser Sintering
TL;DR: In this article, the microstructure of the Ti6Al4V alloy was studied and it was found that microstructural characteristics are related to the building process parameters, and the fatigue performance was evaluated as a function of build orientation.

The Effects of Feature Sizes in Selectively Laser Melted Ti-6Al-4V Parts on the Validity of Optimised Process Parameters.
TL;DR: It was found that there is an acceptable range of sizes that can be produced using a fixed set of parameters and that any set of optimized process parameters will only be valid within a specific size window.

On the effect of throughout layer thickness variation on properties of additively manufactured cellular titanium structures
TL;DR: In this article, the effect of variable throughout layer thickness configuration in the binder-jet additive manufacturing of titanium structures for orthopedic applications was investigated, where two layer thicknesses of 80 and 150μm were selectively controlled inside of each titanium sample with four different configurations.

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.
