Title
Transformation Texture and Microstructure in a controlled Rolled
주정곤Jung Gon Joo, 한봉희Bong Hee Hahn
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}.
