The Atom Probe and Markov Chain Statistics of Clustering
TL;DR: In this article, a Markov chain generalization of the binomial model is proposed to investigate clustering of like atoms within an alloy of two types of metalic elements and a combinatorial analysis is developed which provides the exact distribution of the sufficient statistics and permits small sample comparisons of expectations and mean square errors of estimates with their large sample approximations.

Austenite–ferrite transformation in enhanced niobium, low carbon steel
P. Yan,H. K. D. H. Bhadeshia +1 more
TL;DR: In this article, it has been shown that the amount of niobium in solution in the austenite is primarily responsible for the retardation of the steel's hardenability.

Effect of As4 overpressure on initial growth of gallium arsenide on silicon by molecular beam epitaxy
TL;DR: In this article, an improvement in the smoothness and defect density of GaAs films on Si by lowering the arsenic overpressure during growth of the initial layer (the first 500 A) was demonstrated.

A model for stress in thin layers induced by misfitting particles: An origin for growth stress
TL;DR: In this paper, the authors modeled the stress caused by misfitting particles in thin layers adherent to substrates and illustrated its implications for diffraction stress measurements using magnetron sputtered TiN layers.

An examination of the sources of variation in the measured properties of Fe80B20 glass
J.A. Leake,A.L. Greer +1 more
TL;DR: In this paper, the activation energy and kinetics of crystallisation of Fe 80 B 20 metallic glass reported by several authors differ appreciably, due to temperature lags in DSC; differences in structural state arising from relaxation; and differences in the population of quenched-in nuclei.
