overaged

基本解釋

Some alloys experience an additional solution heat treatment, while other alloys become overaged in the HAZ.
一些合金將使用輔助固溶熱處理，而有些合金將在HAZ中過度時效。
Accordingly the tension macro-fracture configuration is fast shear one at under and peakaged state and the cup-cone fracture arises at overaged state.
拉伸宏觀斷口形貌表明：欠時效和峰時效為快速剪切斷口，過時效出現(xiàn)杯錐斷口。
The results indicate that on the condition of peak aging，the materials show higher resistant to creep than those overaged materials do.
結(jié)果發(fā)現(xiàn)：峰時效下，合金的蠕變抗力強于過時效狀態(tài)下材料的蠕變抗力。
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.
掃描電鏡觀察發(fā)現(xiàn)：隨時效的進行，斷裂模式從欠時效狀態(tài)下以穿晶斷裂為主向過時效狀態(tài)下以沿晶斷裂為主變化。
