Hi you need to calibrate for each temeprature individually via curve fitting tool corresponding to each material model and then use the one global material to combine as function of temeprature by inputtign the those constants. 

however, you also need curve of temeprature dependent thermal properties to be coherent with thermal cycling via thermal conditining or you can use coupled field templet to achive your results. 

Cheers, Ram
