Abstract Scope |
Processing materials is often concerned with obtaining the best possible microstructure, provided that one can obtain the desired shape. Understanding how to achieve this has of course been a main objective of Lee Semiatin’s career. Many aspects must come together such as solidification, plasticity, dislocation structures, stored energy, anisotropy, recrystallization and grain growth. Processing science is therefore a demanding domain because of the thorough scientific knowledge to underpin the phenomenology. Heterogeneity in microstructure must be controlled, whether it be avoiding abnormal grain growth or mitigating the effects of large grains inherited through a phase transformation. 3D printing has reinvigorated metallurgy because it provides rapidly solidified metals in bulk form. Traditional analysis such as TTT diagrams are still useful but must be re-measured for the new processes. Several examples will be given of where understanding microstructural evolution is essential for processing. |
