Lattice parameters and compositions of {gamma} and {gamma}{prime} during coarsening in the Ni-Al-Si system: A neutron powder diffraction study

Journal Article Muralidharan, G ; Univ. of Illinois, Urbana, IL ; Richardson, J W ; ... - Scripta Materialia

Ternary Ni-base alloys are often used as model systems for studying coarsening in multi-component systems. Ni-Al-Ti, Ni-Al-Mo, Ni-Cr-Si and more recently, Ni-Al-Si alloys have been used for such studies. These alloys allow the coherent precipitation of L1{sub 2} phase (Ni{sub 3}X, designated as {gamma}{prime}) from an F.C.C.-solid solution and thus enable the study of coarsening of precipitates in coherent systems. With the improvement in theoretical understanding of coarsening in multi-component systems, phase composition information (composition of precipitates and matrix) has become essential for proper interpretation of coarsening data obtained from ternary systems. However, such information is not readily available formore »« less

Grain boundary formation through particle detachment during coarsening of nanoporous metals

Journal Article Elder, Kate L. M. ; Andrews, W. Beck ; Ziehmer, Markus ; ... - Proceedings of the National Academy of Sciences of the United States of America

Grain boundary formation during coarsening of nanoporous gold (NPG) is investigated wherein a nanocrystalline structure can form by particles detaching and reattaching to the structure. MicroLaue and electron backscatter diffraction measurements demonstrate that an in-grain orientation spread develops as NPG is coarsened. The volume fraction of the NPG sample is near the limit of bicontinuity, at which simulations predict that a bicontinuous structure begins to fragment into independent particles during coarsening. Phase-field simulations of coarsening using a computationally generated structure with a volume fraction near the limit of bicontinuity are used to model particle detachment rates. This model is testedmore »« less

Self-Similarity and the Dynamics of Coarsening in Materials

Journal Article Sun, Yue ; Andrews, W. Beck ; Thornton, Katsuyo ; ... - Scientific Reports

Abstract Two-phase mixtures, from metallic alloys to islands on surfaces, undergo coarsening wherein the total interfacial area of the system decreases with time. Theory predicts that during coarsening the average size-scale of a two-phase mixture increases with time as t ^1/3 when the two-phase mixture is self-similar, or time independent when scaled by a time-dependent length. Here, we explain why this temporal power law is so robustly observed even when the microstructure is not self-similar. We show that there exists an upper limit to the length scales in the system that are kinetically active during coarsening, which we term themore »« less

The mechanism of eutectic growth in highly anisotropic materials

Journal Article Shahani, Ashwin J. ; Xiao, Xianghui ; Voorhees, Peter W. - Nature Communications

In the past 50 years, there has been increasing interest—both theoretically and experimentally—in the problem of pattern formation of a moving boundary, such as a solidification front. One example of pattern formation is that of irregular eutectic solidification, in which the solid–liquid interface is non-isothermal and the interphase spacing varies in ways that are poorly understood. Here, we identify the growth mode of irregular eutectics, using reconstructions from four-dimensional (that is, time and space resolved) X-ray microtomography. Our results show that the eutectic growth process can be markedly different from that seen in previously used model systems and theories basedmore »« less
