The phase selection of hyper-peritectic Al-47wt.%Ni alloy solidified under different pressures was investigated. The results show that Al3Ni2 and Al3Ni phases coexist at ambient pressure, while another new phase α-Al exists simultaneously when solidified

MUCH has been written of the growth of the component crystalline grains which occurs when a metal is maintained at a constant high temperature, but hitherto no simple law of growth appears to have been established. Working with cadmium, we have found laws which hold with precision for that metal.

Due to molybdenum’s Body-Centered Cubic (BCC) crystalline structure, its ductile–brittle transition temperature is sensitive to shaping, purity and microstructure. Dense molybdenum parts are usually shaped by the powder metallurgy process.

Nucleation and growth of dust grains
Classical nucleation theory must be modified for the condensation of small, solid dust grains. Ion nucleation is unimportant and exchange reactions with gas molecules are required. For carbon-rich stellar atmospheres, hydrocarbons act as intermediaries for converting acetylene gas into carbon particles.

Effect of cobalt oxide on the sintering and grain growth of Al2O3-YAG composite nanopowder [PDF]
In the present study, the effect of cobalt oxide on the densification of Al2O3-YAG composite nanopowder was investigated. An amorphous nanopowder was synthesized and crystallized to Al2O3-YAG after heat-treatment via a solid-state reaction.

Phase-Field Simulation of Grain Growth in Uranium Silicide Nuclear Fuel
Uranium silicide (U3Si2) is regarded as a viable fuel option for improving the safety of nuclear power plants. In the present work, phase-field simulations were employed to investigate grain growth phenomena, encompassing both isotropic and anisotropic ...
