摘要
PURPOSE: A method for evaluating dynamic deformation property of structure steel is provided to be utilized as standard capable of determining the safety of a product used in the low temperature. CONSTITUTION: A steel material specimen is prepared(S1). Low temperature torsion of the steel material specimen is tested in the temperature lower than room temperature by using a dynamic torsion test apparatus which includes a refrigerant injection system(S2). Property parameter of the steel material specimen is obtained through a low temperature torsion test(S3). The property parameter is analyzed. Low temperature dynamic deformation property of the steel material specimen is evaluated(S4).
