, the crystallinity of the iPP samples was greatly reduced during deformation, which induced the unclear spherulites and spherulite boundaries. Subsequent heat treatment resulted in the strong recrystallization... in the deformed spherulites. Heat treatment did not change the shape of the spherulites formed during deformation. The recrystallization also resulted in very clear spherulites and spherulite boundaries......

A heat treatment in a low-pressure condition was applied to the as-sprayed TBC system, with the aim......
underwent holding time-free heat treatment was reported.Electron backscattered diffraction analysis reveals that a large number of Σ3 boundaries(600 <111> twin relationship) are produced at the early stage of heat treatment,which is due to the lower boundary energy.With the recrystallization proceeding,the migration rate of grain boundaries decreases on account of the grain growth;meanwhile......
