摘要: |
采用蠕变时效成形技术成形的带筋条壁板,在成形过程中,由于力的加载,加快了稳定相的形成,同时也诱发了惯析面上稳定相的析出,使得经蠕变时效后成形的壁板整体性能得到加强;通过蠕变本构方程的建立,能较好地预测壁板成形后半径,使得壁板型面精度得到大大提高。 |

Abstract: |
For the loading, iso-grid panel manufactured by creep age forming, accelerates the depletion of the solute into precipitates, induces the precipitates forming on the habit plane, strengthens the property of the panel; Constitutive equation of the creep age forming, can predict the radius of the panel and improve the accuracy of the panel. |
