| 摘 要： | 对1Cr18Ni9Ti不锈钢进行了多轴棘轮效应及典型的非比例循环试验研究，表明1Cr18Ni9Ti钢是循环强化材料并表现出明显的非比例循环附加强化。在多轴棘轮试验中，应变幅值、轴向载荷大小及方向对材料强化性能、轴向应变、棘轮应变率有着明显影响。

| Abstract: | A series of multiaxial ratchetting experiments have been conducted on 1Cr18Ni9Ti stainless steel. Present experiments have shown that 1Cr18Ni9Ti was a cyclic hardening material. Strain path had influence on cyclic hardening behavior. Axial stress was the major influence factor on ratchetting strain. The plastic flow property of ratchetting path was different from torsion. |
