1. Precipitates play crucial roles in grain oriented electrical steels and high strength low alloy (HSLA) steels. (Chapter 1)
2. State-of-the-art (scanning) transmission electron microscopy is currently the most powerful technique for characterizing nanoscale precipitates. (Chapters 3 & 4)
3. The dissolution of aluminium nitride based precipitates triggers the growth of centimeter sized grains with sharp Goss texture, which are responsible for ultra-low losses in transformer core steel. (Chapter 3).
4. Accurate determination of the composition, size and volume fraction of precipitates in HSLA steels is only possible by combining complementary techniques like transmission electron microscopy, matrix dissolution method and small angle neutron scattering. (Chapter 4)
5. Dislocation number density determines the recrystallization kinetics of cold rolled HSLA steels. (Chapter 5)
6. Precipitation and recrystallization interact with each other in cold rolled HSLA steels. Simultaneous investigations of precipitation and recrystallization behavior are needed to predict the mechanical properties. (Chapter 6)
7. Don’t lose faith, as long as you persevere, you will get some fruits. (Tsien Hsue-shen)
