Abstract
The structures of two interfaces of martensitic transformations in Cu Zn based alloys have been investigated using computer simulation techniques. A new interatomic potential has been developed which is assumed to represent all interactions between atoms in the parent bcc phase and the product hcp and 9R phases. Stable relaxed structures of bcc/hcp and bcc/9R interfaces have been found. In both cases the interface migrates into the bcc phase during the relaxation process. The boundary in the bcc/hcp computer model is broad involving about 6 (110) bcc planes of atoms, whereas that in the bcc/9R model is simpler involving only 3 planes. This suggests that the 9R product structure might be preferred in practice.
