Embodiment 1
[0024] Example 1: Determination of the recrystallization temperature of 70% cold-rolled deformed H85 brass
[0025] (1) Take a H85 brass sample (length 60mm, width 10mm, thickness 0.5mm) with a cold rolling deformation of 70%, perform three-point bending deformation under the protection of argon, and keep the load constant at 20N;
[0026] (2) Continuously heat the heat treatment furnace at a heating rate of 0.5°C / s, and record the continuous temperature rise load-temperature change curve, such as figure 2 shown;
[0027] (3) Accurately analyze the alloy recrystallization temperature according to the metal material heating load-temperature change curve.
