Microstructure and phase selection in containerless processing of Fe-Ni droplets
Andrea Zambon,B. Badan,K. Eckler,F. Gärtner,A.F. Norman,A.L. Greer,Dieter M. Herlach,Emilio Ramous +7 more
TL;DR: In this paper, a phase selection map was constructed which relates the predominant phases and microstructures (coarse-dendritic or grain-refined) to the composition and the droplet size.

Influence of lipid composition, crystallization behavior and microstructure on hardness of palm oil-based margarines
TL;DR: In this paper, two typical commercial palm oil-based margarines, denoted A (complained as with over-hardness) and B (commercially considered as with acceptable hardness), respectively, were compared in terms of hardness, solid fat content (SFC), lipid composition [fatty acid and triacylglycerol (TAG) composition], crystallization behavior and microstructure.

M. Dahlén,L. Winberg +1 more
TL;DR: In this article, the influence of γ′-precipitate dispersions on the recrystallization behavior of the Ni-base superalloy IN 738 LC has been investigated for a re-stallization temperature of 1120°C.

Annealing and recrystallization of amorphous silicon carbide produced by ion implantation
TL;DR: The annealing behavior of amorphous SiC layers produced by MeV Si implantation into 6H-SiC has been investigated systematically by means of step height measurements, x-ray diffraction, and optical microscopy.

Precipitation sequence in niobium-alloyed ferritic stainless steel
TL;DR: In this article, the authors estimate the volume fractions and particle sizes for Fe2Nb (Laves phase) and Fe3Nb3C (M6C) carbide in a 19Cr 0.8Nb steel with good agreement against experimental data.
