Thermite Weld Property!

Hey all, I am making an educational research on rail-welds, prediction of fatigue life of a thermite weld. and I used Abaqus and FRANC3D for my model but I couldn't get the modules of elasticity, the poissones ratio and the density of the weld from literatures and from codes as well, if there is any with this referrable literature and/or standard i will be so excited.

Thanks,
