Nov 01, 2013 HR-T heat treatment has the highest tensile strength, whereas FC shows the lowest tensile strength at room temperature. At an elevated temperature of 700 C, however, FC has a comparable tensile strength with HR-T and NT. 3) This means that dual phase ODS steel can be significantly enhanced by a proper heat treatment process.

Defects And Distortion In Heattreated Parts

heat treatment provides a very poor impact strength and almost completely intergranu- lar fracture surface after impact failure. This phenomenon is termed burning. Burn- ing thus occurs at a higher temperature than overheating. If this occurs during forging, the forging will often break during cooling or subsequent heat treatment (Ref 4).
