The 825 alloy has a narrow thermoforming section and high deformation resistance. The 825 alloy was subjected to hot compression and hot tensile tests. It was found that the section shrinkage of the 825 alloy during hot stretching increased first and then decreased with increasing stretching temperature. According to the requirements in actual production (the actual shrinkage rate is greater than 50% in the actual production is the thermoplastic critical value), the thermal processing critical temperature value of 825 alloy is T=1240oC, and the thermal processing interval of 825 alloy under high strain rate is 1050 oC <T<1240 oC.
