Coefficient of thermal expansion in austenite transformation
Posted: Tue Oct 10, 2017 4:37 pm
Hello, I would like to ask a question, I want to simulate the process of austenite to ferrite transformation, in the simulation of the coupling of the stress, so in the material data for elasticity recommendations plate need to fill the austenite thermal expansion coefficient .
The coefficient of thermal expansion is defined as the ratio of the length of a solid matter to a length at 20 ° C (ie, a standard laboratory environment) when the temperature changes by 1 degree Celsius. Now we will record the length of the material at 20 ℃ as L0.
For the thermal expansion coefficient of austenite, I collected the experimental data from the literature, L0 is the length of the material at 20 ℃, but this time the material is all ferrite, so I would like to ask, the program in this The corresponding L0 of the thermal expansion coefficient of the austenite to be filled is the length of the ferrite at 20C or the length of the austenite at20 ℃?
