Grain Boundary Segregation and Grain Boundary Diffusion of Carbon in Niobium. Comparison of Data for Substitution and Interstitial Solid Solutions
TL;DR: In this article, the authors studied the effect of grain boundary (GB) diffusion on the transition state energy of C in Nb and also for other intrstitial solutes (P, S) in bcc transition metals (α-Fe, Mo) in a framework of transition state t heory.

On Equilibrium and Stationary Coefficients of Grain Boundary Segregation
TL;DR: In this article, the difference between segregation coefficients b and s and dependence of scoefficient on GB and bulk diffusion parameters will be discussed on the base of experimental data and transition state theory.

Grain boundary diffusion and grain boundary structures of a Ni-Cr-Fe-alloy: Evidences for grain boundary phase transformations
Sai Rajeshwari K,S. Sankaran,K.C. Hari Kumar,Harald Rösner,Vladimir A. Esin,Sergiy V. Divinski,Gerhard Wilde +6 more
TL;DR: In this paper, the grain boundary tracer diffusion of Ni, Fe and Cr was studied in a Ni-base 602CA coarse-grained alloy and a coexistence of several short-circuit contributions was distinguished at higher temperatures in Harrison's B-type regime (773-873 K), which were related to different families of high-angle grain boundaries with distinct coverages by precipitates and segregation levels.

Grain Boundary Segregation Versus Precipitation in Grains. Effect on Diffusion
Boris S. Bokstein,A.N. Smirnov +1 more
TL;DR: In this article, the saturation value of solute segregated in grain boundary, provided all available sites occupied, must be close to the solute concentration, in the nearest in composition phase in grain as it follows from phase diagram.
