The starting temperature of bainitic transform-ation, B_s, has been also calculated according to the shearing mechanism of baini-tic transformation in the carbon depleted regions of austenite. The maximum driv-ing forces for the phase transformation in both 3%Cr containing and CrMo steelsmay be obtained at temperature B_s. It was shown that the proposal of the shearingmechanism of the bainitic transformation is thermodynamically possible.
