thus form a high fraction of intra-globular liquid phase and result in long-stretched
austenite grains parallel to the rolling direction. The 20 min hold at 1250 C, the
subsequent heating to the partial liquid state and the further hold of 5 min at 1400 C
are not sufficient to eliminate the negative influence of the rolled primary material.
