Abstract:

Special misorientations between the laths of martensite packets in a low-carbon structural steel have been investigated by the method of EBSD-based orientation microscopy. It has been established that, in the process of the gamma -> alpha transformation, as a consequence of Kurdjumov-Sachs orientation relationships (ORs), special misorientations of the I 3 pound, I 11 pound, I 33c pound, and I 99a pound types are formed between the laths of a packet. The I 3 pound misorientation is exact, and the remaining misorientations close to the special ones are formed with identical angular deviations as a result of the need to match the misorientations of laths in triple junctions (I 3 pound + I 11 pound -> I 33c pound, I 3 pound + + I 33c pound -> I 99a) pound. Triple junctions of laths also appear in the packet that include a low-angle boundary (LAB) (between two laths of one orientation) and two boundaries of the I 33c pound type, which can lead to the appearance of a boundary of the I 41c pound type (I 33c pound + LAB -> I 41c) pound. The misorientation that corresponds to the I 25b pound boundary discovered in the structure probably appears between the laths as a consequence of the fulfillment of the Nishiyama ORs.
