时效强化 meaning in Chinese

ageing strengthening

The aging curve demonstrated " " double peak "
一合金时效强化曲线呈现双峰结构。
The electric field strengthens the laminate boundary of 2090 alloy . the laminate strengthening mechanism translates into boundary strengthening and grain inner toughening with more ductility fracture and less intergranular fracture . the ductility property is enhanced with no change of intensity
对铝理合金sem实验发现，电场固溶和时效强化了晶界，和晶内塑性的改善，断裂特征出现由分层沿晶断裂向塑性断裂转变，断面塑性变形特征增加。
Contents of re have an effect on the tensile mechanical properties at high temperature to some degree . proper amount of re can improve b & 0 . 2 apparently and 5 a little , because re can form compounds of good thermal stability with magnesium , which can be effectively strengthened by heat treatment
试样中稀土的含量影响试样的力学性能指标_ b (抗拉强度) 、 _ ( 0 . 2 )和延伸率：适量的稀土可显著提高_ b 、 _ ( 0 . 2 ) ，并一定程度上提高其延伸率，这是因为稀土与镁可形成本身热稳定性非常好的化合物，并且可时效强化。
