MECHANICAL-PROPERTIES OF L1(2) INTERMETALLIC COMPOUNDS

Intermetallic compounds with the L1(2) structure exhibit unusual mecha nical properties, whose an anomalous increase in flow stress with temp erature. These mechanical properties, that are strongly dependent on a lloy composition, temperature and sample orientation, are briefly revi ewed in the present paper, in order to assemble the whole macroscopic characteristics of L1(2) intermetallic compounds which have to be expl ained by the various dislocation models that have been proposed to dat e or will be elaborated in the near future.
