Formation kinetics of crystalline Si3N4/SiC composites from amorphous Si-C-N ceramics
TL;DR: In this paper, the crystallization kinetics of amorphous precursor-derived bulk ceramics of composition Si26C41N33 were investigated in the temperature range between 1500 and 1645 °C using X-ray diffractometry.

Precipitate phases in type 316 austenitic stainless steel resulting from long-term high temperature service
TL;DR: In this paper, the precipitate phases in a type 316 steel superheater tube which failed by creep were studied by using a newly developed X-ray internal standard technique and scanning transmission electron microscopy.

Isothermal nature of martensite formation in Pt-modified β-NiAl alloys
Daniel J. Sordelet,Matthew F. Besser,Ryan T. Ott,Benjamin J. Zimmerman,W. D. Porter,Brian Gleeson,Brian Gleeson +6 more
TL;DR: In this paper, it was shown that the martensite transformation is isothermal in nature with a single activation energy, and that the temperature range where this reversible transformation occurs increases with higher Pt contents, where a series of "bursts" corresponding to a sequence of individual exothermic peaks were observed.

The β to ζ massive transformation in Ag-Al alloys
TL;DR: In this article, the progress of a single β ζ m reaction interface has been studied as a function of undercooling and cooling rate during the β to ζm massive transformation in Ag-24.5 at.% Al and Ag-25.9 at.%.

A kinetic treatment of glass formation V: Surface and bulk heterogeneous nucleation
H. Yinnon,Donald R. Uhlmann +1 more
TL;DR: In this paper, an analytical method is described for calculating the detailed distribution of crystallite sizes in a supercooled liquid, and the changes in this distribution as a function of temperature (time) while the liquid is cooled from above the melting point.
