Effect of cooling rate in variant selection during bainite transformation in heat affected zone of Cr-Mo steel

The effect of the cooling rate on the variant selection mechanism during bainite transformation was investigated in 2Cr- 1Mo steel. The specimen was heat treated to 1350 ℃ and held for 60s before being cooled to room temperature with various cooling rates. The usage of high temperature laser scannin...
