Abstract
The methods of x-ray diffraction analysis and optical metallography were used to study the crystallography and morphology of martensite in alloy Ti50Ni40Cu10. It was found that polytypic structures of monoclinic martensite B19′ with 2H- and 4H-packings are formed in forward and reverse martensite-martensite transformations, while the morphology of martensite B19′ is pyramidal. Martensite transformation into a B2-superstructure develops through the formation of new martensite B19 pyramids near previously formed pyramids, each of them being formed by the burst mechanism.
