摘要：

The present work analyses the microstructure of quenched and cyclic compressed Ti-Mo alloys that possess non-elastic effects and reversible martensitic transformations. Quenched samples were subjected to cyclic compression tests up to 10% strain per cycle. The structure of these alloys, composed of beta (BCC) phase with minor participations of alpha' (HC); alpha '' (orthorhombic); w (HCC) and alpha (HC) phases, apparently had suffered a gradual alpha -> alpha' -> alpha '' -> beta transformation with increasing Mo content. It was found that the cyclic compression did not promote relevant alterations in the phase composition. Both the alloys electrical resistivity and microhardness were found to be sensitive not only to the Mo content but also to the accumulated deformation. Alloys with 8 and 10% Mo content exhibited low elastic modulus combined with low residual strain, which indicates a possible superelastic behavior.
