研究了LC9铝合金棒材在室温下的形变硬化规律。测量了真应力应变曲线。得到了均匀形变阶段和非均匀形变阶段的真应力应变关系。进行了缩颈区应力修正,对试样颈部表面作了初步讨论。
The deformation and hardening of LC9 aluminum bar at room temperature were studied. The true stress-strain curve was measured. The true stress-strain relationship between the uniform deformation phase and the non-uniform deformation phase was obtained. The neck area stress correction was carried out, and the neck area of the sample was preliminarily discussed.
