Hot Deformation Behavior of metal an important aspect of research is to study the metal in the process of hot deformation behavior of the flow stress, as well as changes in the law of the mechanical properties of the macro-response behavior is the flow stress. According to the theory of deformation, the flow stress of metal materials in a one-way refers to the deformation conditions sufficient to achieve plastic deformation of the stress intensity. Metals and alloys in the plastic working process, the flow stress determined the deformation of the size of equipment needed to load and the size of the required energy consumption. Generally speaking, the impact of the metal flow stress factors in general can be divided into internal factors and external factors. The main external factors, including deformation temperature, strain rate and strain (deformation), they are internal factors of the flow stress of metallic materials. Deformation temperature on the impact of flow stress as follows: flow stress with deformation temperature lower, but reduced somewhat different, that is, the higher strain rate, with the increase in deformation temperature, flow stress gradient reduced more Great. Strain rate on the impact of flow stress: the higher the strain rate, the greater the value of flow stress, and increase the flow stress with temperature changes, temperature, the higher the lower the rate of increase. The rate of increase of flow stress is not maintained at a fixed value, but as the strain rate changes. Internal factors include the chemical composition of metals, metal the microstructure changes such as dynamic recovery and dynamic recrystallization, such as work hardening. High-temperature mechanical deformation of metallic materials from high temperature creep behavior of metals on the basis of developed. Metals and alloys the existence of thermal processing thermal activation process, the strain rate thermal activation process control. Deformation under different conditions using different expressions, but also related to thermal activation, the dislocation movement, such as the micro-mechanism. This paper AZ31 magnesium alloy sheet for the study, the RG-based microcomputer-controlled universal testing machine, metallographic microscope and scanning electron microscopy tools, research and analysis of magnesium alloy at different temperatures forming performance, flow stress and microstructure changes in the law. The following conclusions: 1. Extrusion, cross-rolling, cold-rolled, hot-rolled, as well as the level of casting AZ31 magnesium alloy sheet metal microstructure is equiaxed structure, the grain size of 5 ~ 25μm; 2. Extrusion of magnesium alloy sheet metal grain size is about 5 ~ μm, the strain rate is less than , the deformation temperature is higher than 150 ℃, the extension rate of greater than 45%, and with the strain rate lower or raise the temperature of the peak flow stress also be reduced accordingly. When the temperature is 425 ℃, then the peak steady-state flow stress is almost equal to the flow stress at the time that the peak stress does not appear, and its value in between 18 ~ 20MPa, and the extension rate of 132%. 3. Cross-rolled sheet metal so that the peak flow stress decreased significantly increased plasticity. (And can reduce or eliminate the anisotropic material to improve the performance of its punch, so that elongation of the material significantly increased for deep-drawing deformation even provided a good internal organization.) At a temperature of 425 ℃, strain rate is less than , the elongation δ> 225%, alloy shows superplasticity. 4. 250 ~ 425 ℃ temperature range, semi-continuous casting + annealing cold-rolled sheet before and after the stress - strain curve changes little elongation δ are greater than 65%. Cold-rolled sheet can be used directly in temperatures greater than 250 ℃ forming thermal processing. 5. At a high temperature to soften and as a result of the role of dynamic recrystallization results of horizontal continuous casting + anisotropic cold-rolled sheet has been significantly improved. At 250 ℃ when the sheet are an extension of the rate of 118 percent, the smallest anisotropy alloys. 6. At a temperature less than 220 ℃, the fracture morphology of the main axis for large and small dimples, such as composition, surface tear edge clarity, and depth of dimples smaller size; When the temperature is greater than 240 ℃ when the equiaxed the edge of dimples appear fine grains, the occurrence of a fracture. Magnesium alloy at high temperature phase of the basic fracture along fracture, with the strain rate increased, the fracture mode transformed to the ductile fracture trend. AZ31 magnesium alloy in the plastic deformation occurred during the dynamic recrystallization and grain growth.
