Superplastic Pb-Sn alloys were produced via tube high-pressure shearing ( t -HPS), in a single step starting from elemental solid bulks. A Pb-40 wt% Sn alloy showed an exceptional superplastic elongation as high ∼1870% at strain rate of 1.0 × 10 −3 s −1 room temperature, thereby elevating the optimum for maximum under these conditions by more than one order magnitude over conventional cast allo...

LPBF of Al alloys is associated with numerous challenges when compared to other commonly used due their higher reflectivity and thermal conductivity. In this work, processing diagrams, temperature prediction models, XCT, metallography are for establishing criteria in process parameter optimization high based on AlSi$_{10}$Mg response using 57 different combinations - 21 a focused Gaussian laser...

In this work we review our new methods to computer generate amorphous atomic topologies of several binary alloys: SiH, SiN, CN; binary systems based on group IV elements like SiC; the GeSe2 chalcogenide; aluminum-based systems: AlN and AlSi, and the CuZr amorphous alloy. We use an ab initio approach based on density functionals and computationally thermally-randomized periodically-continued cel...

Aluminum alloys containing transition metal alloying elements have attracted interest from researchers. The effect of Cr additions 0.25 and 0.50% on the thermal profile, microstructure, hardness, linear reciprocating sliding wear response as-cast hypoeutectic Al–Cu with 2.5, 3.5, 4.5% Cu (wt.%) was investigated. binary ternary Al–Cu–Cr were directionally solidified under upward non-steady state...

Metal matrix composite (MMC) technology can improve the service performance of matrix metals and alloys. Most magnesium alloy based MMCs are produced via a casting process, therefore the casting microstructures are of vital importance to their performance in service. The formation of microstructure during solidification of MMCs is mainly influenced by four factors: nucleation (or its absence) o...
