|
| The internal friction spectrum at 5 MHz in the martensite beta'(1)-phase of CuAlNi alloys shows two prominent internal friction peaks at 270 and 170 K. Corresponding anomalies in the sound wave velocity-temperature dependence have been observed. Detailed analysis of the behaviour of the peaks in dependence on different levels of impact loading and gamma-irradiation points to dislocation-point defect interaction. It is assumed that grain boundary dislocations are responsible for the 270 K peak while lattice dislocation, existing within the martensite variants are responsible for the 170 K peak. |
