Study on Mechanical Relaxations of 7075 (Al–Zn–Mg) and 2024 (Al–Cu–Mg) Alloys by Application of the Time-Temperature Superposition Principle
Figure 5
Master curve showing the storage modulus versus the logarithm of the frequency times the shift factor . These curves resulted from horizontal shifting of the isothermal curves from DMA tests on AA 7075-T6 and solution treated AA 7075, at temperatures from 50 to 155°C.
