Strain Measurement by Intra-granular Distortion Analysis in Creep of 2.25Cr-1Mo Steel
Intra-granular creep distortion of 2.25Cr-1Mo steel deformed at 843K and 106MPa has been investigated by transmission electron microscopy (TEM). Intra-granular distortion detected by Kikuchi pattern shifting was observed quite early (
