There is no such thing like a stress / strain curve of Sn63 because of its creep behaviour. What I can offer you is:

- Stress / strain rate curve with the temperature as parameter
- Constitutive equation Strain rate = f ( Stress, Temperature )

Both ( for Sn62Pb36Ag2)  you find in the proceedings of the 1997 IEMT Symposium, IEEE Catalogue Number 97CH36068

Title: Lifetime Assessment of Solder Joints on the Base of the Metallurgical Behaviour of Sn62Pb36Ag2

Have a great day
