1972Wayman & Shimizu in Metal Sci. Jrnl. VI. 175/2 The present authors comment on the shape memory effect with particular regard to the crystallography of martensitic transformations. Since the balance of experimental evidence indicates that it is the martensitic phase which exhibits a memory, the term ‘marmem’ is introduced as descriptive of the general behaviour. 1979Guardian 18 June 3/1 A technological revolution called the ‘marmem effect’ in which a shape can be built into a metal component and ‘remembered’ at any chosen temperature. 1979Sci. Amer. Nov. 70/3 In the marmem alloy of copper, zinc and aluminium four variants of martensite form out of the parent beta phase, each with a crystal orientation displaced by 60 degrees from the others. 1986Materials Sci. & Technol. II. 496 The influence of parent phase chemistry on the marmem behaviour of Cu–Al–Ni and Cu–Zn–Al alloys has been studied. |
