Martensite and hydride transformations in the V-N-H and V-O-H systems

Optical metallography has been applied to vanadium containing traces of oxygen and nitrogen on electrolytic saturation with hydrogen; a martensite phase is formed near room temperature and above (formation controlled by the H/V concentration), and hydrides segregate, which suppress further martensite growth.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 39–42, March, 1990.
