| 1 | An Internal State Variable Model for the Low Temperature Tempering of Low Alloy Steels显示文摘An internal state variable (ISV) framework is used to predict the rate and degree of strain relaxation associated with the stage I, low temperature tempering of martensite. A single variable tracks the change in volume between the tempered an untempered structures. The rate at which this occurs is taken to be a function of martensite fraction, temperature, degree of tempering, and carbon concentration. Experimental dilatometty data is used to both fit and validate the model. | Mark T. Lusk, Young-Kook Lee, Herng-Jeng Jou, William H.
