Microstructural Evolution in Ni Alloys

This lecture covers the microstructural evolution in Ni alloys, focusing on topics such as microsegregation, heat treatment, mechanical properties, and high-temperature performance. It discusses the formation of various grain boundaries, microsegregation in single-crystal alloys, and the effects of heat treatment on strengthening mechanisms. The lecture also explores the challenges in designing Ni superalloys, the role of alloying elements, and the classification of Ti alloys. Additionally, it delves into the oxidation behavior of titanium alloys and the strengthening mechanisms employed in Ti alloys.
