VISCOELASTIC BEHAVIOR IN INDIUM ALLOYS - INSN, INBI, INCD AND INSNCD

Experimental studies of dynamic and transient viscoelastic response we re conducted at 24 degrees C on the indium alloys InSn, InBi, InCd and InSnCd. The experiments were conducted in torsion using an instrument capable of determining viscoelastic properties over ten decades of ti me and frequency. The damping, tan delta, followed a v(-n) dependence at higher frequency v and was essentially constant at low frequency. C reep at long times followed a power law dependence upon time: t(m). Th e damping is attributed to a dislocation-point defect mechanism.
