材料论文翻译

我已经把文章发到你的邮箱~请查收

算了 我比较爱国

论文网找的，比较短哈，不过不会和别人的重复，
因为是我自己发现的论文网（加分的话，我把自己收留的所有论文网发给你邮箱，呵呵，卑鄙吧...）

有漏洞你修改一下哈～

(1) Discontinuous coarsening mechanism.It was previously found that spinodal decomposition firstly occurred in the solution-treated Al-Zn-(Cu) alloys held at 2500C for different time, which
was slightly below the eutectoid temperature; thenthe spinodal microstructure transformed into the fine lamellar one by DP DP completely ended in 30 min in AlZn alloy, while in 20 min in AlZn-2Cu alloy [5].However, the fine larneflar microstructure was still unstable. When the sample of AlZn alloy was held at
250℃ for 2 h, discontinuous coarsening (DC) cells formed at the primitive boundaries and cellular boundaries of DP (figure 1(a)). With the increase of aging time, discontinuous coarsening cells swal-lowed up the fine lamellar microstructure by the mi-
gration of cellular bound
