Effect of composition and process variables on Nb(C, N) precipitation in niobium microalloyed austenite
B. Dutta,C. M. Sellars +1 more
TL;DR: In this article, the authors used nucleation theory and the solubility product of niobium, carbon, and nitrogen in austenite to derive equations for the start of Nb (C, N) precipitation as a function of temperature and composition.

Jeffrey J. Thomas,Joseph J. Biernacki,Jeffrey W. Bullard,Shashank Bishnoi,Jorge S. Dolado,George W. Scherer,Andreas Luttge +6 more
TL;DR: In this paper, a review of recent efforts to model and simulate the highly complex cement hydration process over the past 40 years are reviewed, covering different modeling approaches such as single particle models, mathematical nucleation and growth models, and vector and lattice-based approaches to simulate microstructure development.

In situ X-ray observations of the coesite-stishovite transition: reversed phase boundary and kinetics
TL;DR: In this paper, the phase transition between coesite and stishovite was identified by observing the first appearance of a phase that did not already exist or by a change in the relative intensity of the two patterns.
