采用准静态拉伸试验方法研究Inconel 718合金的加工硬化特性.结果表明,Inconel 718合金加工硬化规律基本遵循Hollomon公式.合金在退火态和冷拔态的应变硬化指数n分别为0.476和0.153,拟合方程式的相关系数分别为0.89和0.99.室温条件下,Inconel 718合金塑性变形阶段的真应力-真应变关系可用Voce型公式描述,拟合方程式的相关系数大于0.99. |

The work hardening behavior of Inconel 718 at the room temperature is studied by quasi-tensile test. The results show that the work hardening kinetics of Inconel 718 is consonant with the Hollmon Equation both for the as-annealed Inconel 718 and as-cold-rolled Inconel 718. The strain-hardening parameters.n are 0.476 and 0. 89, respectively. The interrelated factors'for equation fitting are 0. 153 and 0. 99, respectively. At ambient temperature, the plastic deformation' stage of the true stress-strain curves of Inconel 718 can be expressed by Voce Relationship, and the interrelated factors for equation fitting are; both over Q, 99. |
