Add Nitinol in the material library (Inventor)

I was wondering if there is a way to import or add Nitinol alloy into my Inventor material list. I need to do stress simulations and Nitinol is not included... 

Any help would be greatly appreciated...

I don't want to spoil your fun, but modeling Nitinol is tremendously difficult. Typically this is done at the element level (e.g., in ABAQUS) because the material is non-linear and coupled in both strain and temperature, plus it's hysteretic and history-dependant; unless you're going to implement a material model somehow, I don't know what you hope to achieve.  By order of magnitude you could assume the martensie phase behaves like copper and the austenite phase like aluminum; but'd be using linear mechanics for a highly non-linear material and your results will be inacurate.
