1. The electric fields decrease the size of pfz and promote the precipitation of p " phase
   电场固溶和时效均减小了pfz的尺寸。
2. Besides , the electric field increses both average particle size and of 8 " phase and the half width of pfz
   电场时效还增加了相颗粒的平均尺寸和pfz的半宽。
3. It is found that the electric , field improves elongations in 2090 and 2090 + ce alloys markedly , especially in 2090 alloy , but has little effect on strengths . at the same time , the electric field lessenes percentages of intergranular delamination and increases transgranular fracture and microscopic plastic deformation . besides , the electric field makes both average particle size and its distributing range of 8 " phase smaller , and reduces the half width of pfz in aged alloys
   研究表明：固溶电场可显著提高2090合金及2090 + ce合金的延伸率，尤其是对2090合金，但对强度则无明显的影响；同时，固溶电场减少合金的沿晶分层断裂比例，并增加穿晶断裂及微区塑性变形；固溶电场还使合金时效后相颗粒的平均尺寸减小、尺寸分布范围减小，并使pfz的宽度减小。
