Comparison of simulated and measured grain volume changes during grain growth

Characterization and Investigation of Grain Selection in Spiral Grain Selectors during Casting Single-Crystal Turbine Blades

Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...

Grain boundary energy and grain growth in Al films: Comparison of experiments and simulations

Relative free energies of h111i tilt boundaries in 1.7-lm-thick Al films were compared with boundary enthalpies obtained via molecular dynamics simulations. Grain growth studies in 25 and 100-nm-thick Al films were compared with simulations. The sources of the differences between experimental and simulational results are discussed. 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights...

Sensitivity of Texture Development during Grain Growth to Anisotropy of Grain Boundary Properties

Evolution of the Grain Boundary Character Distribution in Strontium Titanate during Grain Growth

Previous experimental results have shown the grain boundary plane distribution (GBPD) for a given material to be anisotropic and approximately inversely correlated to the anisotropic grain boundary energy distribution. The goal of the present work is to quantify how the anisotropic GBPD evolves during processing. Interrupted grain growth experiments were performed to observe the evolution of th...
