摘要：

The mechanical behavior of superplastic 5083 aluminum alloy during microforming process was investigated by finite element analysis. A micro V-groove die was modeled to analyze the effects of forming time, load and temperature on the microformability of the 5083 aluminum alloy. First, the microformability of the 5083 aluminum alloy was estimated using a microformability index. The simulation results show that the microformability increases with the forming load, time and temperature increasing. Superplasticity of the 5083 aluminum alloy during microforming using the V-groove die was also investigated in terms of the effective strain rate. The results show that the superplasticity of the 5083 aluminum alloy occurs in a specific part of the material for a specific period during the microforming process depending on the forming conditions and the microformability index.
