How Do I Find Constants for the JC Flow Stress Model in Waspaloy?

[federico_spada]

Hi my name is Federico and I'm a student of mechanical engineering and i have to make a research on this material: waspaloy. Now, i have the flow stress model, but i don't have some constant of this equation. In particular , there are a classic JC model where stress is:
stress=[A+B*(def)^n]*(...). A is defined as: A=a + k/sqrt(d), where "a" and "k" is a constant and "d" is a grain size. Can someone help me? Thank you to all.
