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

Grain refinement of additively manufactured stainless steel by ultrasound
TL;DR: In this paper, high-intensity ultrasound was used to control the solidification process during AM of 316L stainless steel, which can promote the formation of fine equiaxed grains with random crystallographic texture.

Effect of thermal behavior on the grain morphology and dimension of 80-mm-thick Ti6Al4V plates joined by laser melting deposition
TL;DR: In this article , two 80mm-thick Ti6Al4V plates were successfully joined using three different scanning speeds (10, 15, and 20 mm/s) and quantitatively analyzed the effects of thermal behavior on the grain morphology and dimension of deposition area, equiaxed crystal zone (EQZ), and the substrate at different scan speeds.
Refinement of the microstructure of light alloys using ultrasonic and laser processing
TL;DR: In this article, the use of aluminum (Al) to reduce vehicle weight offers the potential to reduce these emissions, and the production of secondary Al from recycled products requires only ~2.8 kWh.

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.
