TL;DR: In this article, the microstructures of the obtained cermets were observed by scanning electron microscopy and compared to those of a Mo-free cermet and a cermet prepared using pure Mo powder.

TL;DR: In this article, porous NiTi-based shape-memory alloys were aged at different temperatures and holding times to study the effects of high O contents on the composition, microstructure, phase-transformation behavior, and shape-recovery properties of SMAs.

TL;DR: In this article, a granular model with an interstitial power-law fluid was used to simulate the filling process in powder injection molding (PIM), enabling direct prediction of the density distribution.

TL;DR: In this article, the authors investigated the sintering neck growth behavior of pure titanium powder with different oxygen contents and found that surface diffusion is the dominant diffusion mechanism, but under the hindrance of oxygen in the matrix, both surface diffusion and grain boundary diffusion slow down.

TL;DR: In this article, gas and water atomised 316L stainless steel powders with similar powder morphology and particle size were injection molded and sintered, and microstructural analysis revealed that SiO2 particles dispersed as a second phase in the compacts prepared from the atomised powder, which accounts for the property behaviour.
