In this work, we present a software package in Python for high-throughput first-principles calculations of thermodynamic properties at finite temperatures, which refer to as DFTTK (Density Functional Theory Tool Kit). is based on the atomate and integrates our experiences last decades development theoretical methods computational software. It includes task submissions all major operating system...

Understanding the macrosegregation formed by applying magnetic fields is of high commercial importance. This work investigates how static magnetic fields control the solute and primary phase distributions in four directionally solidified alloys (i.e., Al-Cu, Al-Si, Al-Ni and Zn-Cu alloys). Experimental results demonstrate that significant axial macrosegregation of the solute and primary phases ...

In the present study, we investigated effects of Cu or Ni additions on precipitation intermetallic phases in heat-resistant aluminum alloy with a ternary composition Al–5Mg–3.5Zn (mol%). The quaternary alloys 1 mol%Cu mol%Ni content were solution-treated at 480°C and subsequently aged 300°C for different periods. Both have slight effect age-hardening these 300°C. added element partitioned into ...

In this paper, laser welding Ni to Al using pulsed wave (PW) and continuous (CW) lasers was investigated. Weld quality strength were evaluated in terms of cross-section examination, intermetallic compounds formation, microhardness, shear test 90-degree peel test. The results show that deep penetration causes high melting pool temperature severe material mixing, which could result dominant AlNi3...
