| Abstract |
Using the method of crystallite orientation distribution functions analysis, the main components of the transformation textures in the controlled rolled high strength 3.4Ni-1.5Cr-0.4Mo steel were studied. The transformation textures of Ni-Cr-Mo steel were compared with the experimentally determined transformation textures of austenitic Fe-27Ni-0.28C steel similarly processed and the deformation textures of the parent phase prior austenite were deduced from the deformation textures of the austenite in Fe-Ni-C steel. It has been found that the main omentations of transformation textures in Ni-Cr-Mo steel finish rolled below the dynamic recrystallized temperature of the austenite are {332} and a fibre texture running from {112} to {111} with a maximum at {223} and those rolled at the dynamic recrystallized temperature are {032} and {331}. Comparison with the transformation textures in Ni-Cr-Mo and Fe-Ni-C steel showed that the deformation texture for prior elongated austenite in Ni-Cr-Mo steel could be expressed as a {110} texture with components {123} and {112}. |
