On the Measurability and Predictability of HAZ Softening in GMAW of Automotive DP980 Steel
Metals, 2022 Dual Phase (DP) steel, composed of a ferrite matrix with dispersed islands of martensite, has become popular in auto-body car construction due to its outstanding mechanical properties (i.e., high strength and good ductility).

Advanced Engineering Materials, EarlyView.Spatial distribution of microstructure in Inconel 718 3D‐printed with bidirectional strategy with no rotation and chessboard strategy is studied. The former results in a highly ordered arrangement of coarse grains separated by line clusters of dislocation‐dense fine grains. This arrangement is disrupted by the chessboard strategy.

Tensile and superelastic behaviors of Ti-35Nb-2Ta-3Zr with gradient structure
Materials & Design, 2020 We investigated the tensile and superelastic behaviors of Ti-35Nb-2Ta-3Zr processed by double-faced friction stir processing that results in a roughly 2 times higher yield strength with an elongation of 37%.

Multiple beam steering using dynamic zone plates on a micro-mirror array [PDF]
, 2017 Three dimensional laser beam steering has been demonstrated using a single optical device -a DMD micro-mirror array. Laser beam focus position is controlled using dynamically adjustable zone plates. These zone plates take the form of elliptical Fresnel zone plates or other variations such as binary Gabor zone plates. Active beam control can be realised

Advanced Engineering Materials, EarlyView.Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.
