and studied the creep [9 the. constructed the. a two-dimensional deformation mechanism diagram in a single-phase and quasi-single-phase alloy, as well as a two-dimensional. deformation mechanism diagram in a two-phase alloy. Deformation mechanism diagram is a useful tool for describing deformation mechanism, the development process is detailed in the literature Abstract Dislocation creep is one of creep mechanisms. Elucidating creep mechanism is beneficial to understand the nature of high-temperature creep deformation and control the slow deformation of service devices at elevated temperatures and their accuracies of dimensions. In this paper, a factor α, was proposed to determine quantitatively the mechanisms of dislocation viscous glide (solute drag creep) and climb. When α>1, dislocation viscous glide or solute drag creep dominates while when α<1, dislocation climb dominates. A calculated example was given, and a three-dimensional histogram was constructed in Al-1.44Mg-1.09Y alloy tensile at elevated temperatures. The results revealed that at 773 and 793 K and at an initial strain rate of 1.67×10 , the rate-controlling mechanism is dislocation viscous glide or solute drag creep, whereas under other conditions, the rate-controlling mechanism is dislocation climb. Bit-wrong creep is one of the mechanisms of creep. It is of great significance to reveal the material creep mechanism for understanding the essence of high temperature deformation of material and the precision of slow deformation control of high temperature service devices. In this paper, a judge factor of determining the misalignment of the bit viscous slip (solute drag creep) and the climbing mechanism is alpha. The misalignment of the sliding mechanism is the dominant mechanism when alpha is 1, and when alpha-lt;1, the misalignment mechanism is the dominant mechanism. An example of calculation is given and a three-dimensional hele chart is constructed in the Al-1.44Mg-1.09Y alloy stretched at high temperature. The results show that under the conditions of temperature of 773K and 793K and strain rate of 1.67 x 10 , Under conditions, the speed control mechanism is mispositioned viscosity slip or solute drag creep, and under other conditions, the speed control mechanism is the faulty climbing mechanism [1-4].
