TL;DR: In this paper, a dual-frequency electromagnetic field was developed to smelt the solid metal and confine the molten metal into a final shape without any contamination, and the process of the dualfrequency electromagnetic containerless confinement is controlled more easily than that of a single frequency electromagnetic confinement.

TL;DR: In this article, the microstructure of the [001] oriented single-crystal superalloy NASAIR 100, solidified respectively with the planar, cellular, coarse-dendritic, and fine-Dendritic solid/liquid interfaces, deformed at 1050 °C and 160 MPa, was investigated with the attempt to reveal the variation of γ′ structures in the necked zones of creep specimens and furthermore to explain that the dendritic single crystals constantly possessed superior stress-rupture lives.

TL;DR: In this paper, the authors investigated the effect of solidification path on the microstructure of the ternary oxide in a high temperature DTA and laser floating zone (LFZ) directional solidification method.

TL;DR: In this paper, the phase constitution, macro/microstructure evolution and mechanical properties of binary TiAl alloys were investigated systematically, and it was found that the shape changing of Ti2AlC was in accordance with the morphology of lamellar colony.

TL;DR: It is demonstrated that the reaction constant (f) which is used to characterize the kinetics of peritectic reaction is crucial for the determination of the detachment process.
