【Abstract】 Undercolling austenite in T12 steel can be directly decomposed into spheroidizing sturcture P_s by means of cantrolling cooling.Furthermore,the degree dispersion and hardness of the structure can be adjusted by cantrolling technological parameters.Then the conditions and principles for controlling cooling spheraidizing are studied.更多还原
