Changing material properties in the middle

Im doing a simulation that is broken into two time steps (think of temperature ramp up and down). I want my material to change some of its properties at the transition (e.g. for T=0 to 1, expansion CTE is 100, and for T=1 to 2, expansion CTE is 200).

How can I do this in ABAQUS/CAE? Ive split up the simulation into two time steps and am changing loading (temperature field) in the second step. I cant simply do two independent simulations with different initial conditions since Id like to keep the state of my elements when the first time step finishes.

Thanks in advance.

I think you can make your material properties dependent on an external field. Then you can simply change the value of the external field between your two steps...
