overaged

基本解释

Some alloys experience an additional solution heat treatment, while other alloys become overaged in the HAZ.
一些合金将使用辅助固溶热处理，而有些合金将在HAZ中过度时效。
Accordingly the tension macro-fracture configuration is fast shear one at under and peakaged state and the cup-cone fracture arises at overaged state.
拉伸宏观断口形貌表明：欠时效和峰时效为快速剪切断口，过时效出现杯锥断口。
The results indicate that on the condition of peak aging，the materials show higher resistant to creep than those overaged materials do.
结果发现：峰时效下，合金的蠕变抗力强于过时效状态下材料的蠕变抗力。
By SEM it has been found that, with the increase of aging time, the fracture model changes from predominantly transgranular at underaged condition to intergranular at overaged condition.
扫描电镜观察发现：随时效的进行，断裂模式从欠时效状态下以穿晶断裂为主向过时效状态下以沿晶断裂为主变化。
