Despite the fast cooling rate (200 °C/min), ... the primary difference between compression and tension creep is thought to occur in the tertiary creep stage where cavitation, void formation, and cracking take place. WebFeb 1, 2005 · Primary nucleation involves the formation of a crystal in a solution containing no existing crystals. Secondary nucleation involves the production of new crystals in a solution containing pre-existing crystals, e.g. by fragmentation. In general sonocrystallisation exhibits a number of features specific to the ultrasonic wave.
