11. There is little melting and minimum grain growth , but a definite bond and grain interface. 12. This effectively controlled discontinuous grain growth . 13. Liquid phase sintering was successfully applied to improve grain growth of thin semiconductor layers from nanoparticle precursor films. 14. Grain growth is the process of grain boundary motion and Ostwald ripening to increase the average grain size.15. The compelling reason for shortening the cycle time then was to avoid grain growth and also save energy. 16. Generalizations of the Potts model have also been used to model grain growth in metals and coarsening in foams. 17. This effect is often exploited in commercial alloys to minimise or prevent recrystallization or grain growth during heat-treatment. 18. Grain size is kept at a minimum as grain growth can happen quite easily if the blade material is overheated. 19. The subsequent cooling and combination of the materials forms a nugget alloy of the two materials with larger grain growth . 20. Discontinuous ( abnormal ) grain growth , where one grain grows at a much greater rate than its neighbours . ]]
