2.During two cooling methods, whether tension stress or compression stress, the retained austenite in steel reduced with stress increasing, had become from massive to streak or filminess.
2.More specifically, these alloys undergo a transformation from a low-temperature, less ordered phase (martensite) to a high-temperature, more ordered phase (austenite), enabled by the unique alloy compositions typically involving metals such as nickel, titanium, copper, and zinc.
