[MW:11904] P91 Weld - Ni and (Ms - Mf) temperature correlation

Dear All,

What is the effect of Ni (Nickel) in Ms (Martensite start) and Mf (Martensite finish) temperature in ASTM A 335 P91 welding?I have searched a lot for the last couple of weeks and found some literature.But none of them describes this phenomena in depth.

Could you please provide a graph which shows Nickel percentage and it's effect in the Ms and Mf temperature in ASTM A 335 P91 weld?


Regards,

Limesh
