Experimental tests have been carried out by applying a constant stress to the materials under study (Al-99.8% as well as AA6061alloy) and increasing the temperature from room temperature to 800K. The heating rate used was 2K/min. We implemented the three-dimensional random-field Ising model, both as...

| Resumo: | Experimental tests have been carried out by applying a constant stress to the materials under study (Al-99.8% as well as AA6061alloy) and increasing the temperature from room temperature to 800K. The heating rate used was 2K/min. We implemented the three-dimensional random-field Ising model, both as function of stress and as a function of temperature for cubic supercells of 16×16×16 sites. We also investigated the behavior of the secondary creep strain rate ε ˙_SS as a function of temperature at different disorder strength ∆ = 0, 0.5, 1, 1.5, 2, i.e. different applied stress. |
