The results show that all the initial bainites formed in different alloys at different temperatures are with three-dimensional ledges on the broad faces and/ or at the growth edges of α1 plates but without internal stacking faults, which proves that ledges exist generally on bainites in Cu-Zn-Al alloys and that the growth of bainites is govern.

非溢流重力坝
non-overflow gravity dam

  feiyiliu zhongliba非溢流重力坝(non一overflow gravitydam)坝顶不溢流的重力坝。各种型式的重力坝都可以建为非溢流坝。筑坝材料多用混凝土,中小型工程也可用浆砌块石。 在大多数重力坝枢纽中,于河床中部或主流部分布置溢流重力坝,两侧布置非溢流重力坝与岸坡相接,其间用边墩和导墙隔开(见重力坝图2)。少数工程,如中国刘家峡水电站,由于河谷狭窄,需布置电站厂房,岸边又有适宜条件布置溢洪道,经方案比较,设置了河岸式溢洪道,拦河坝全部为非溢流重力坝。非溢流重力坝可根据调洪预泄、放空水库、排沙等运用要求在坝身布置深式泄水孔。当有坝后厂房时,可穿过坝体布置发电引水管。 非溢流重力坝的坝体设有横缝、纵缝、止水、排水、廊道等(见坝体分缝、止水、坝内排水管、坝内廊道)。进行非溢流重力坝剖面设计时,常先拟定基本剖面,再根据运用和施工要求修改成为实用剖面(见重力坝剖面),然后进行详细的稳定和强度计算(见重力坝应力分析和重力坝抗滑稳定),根据计算结果再进行修正。为减小计算工作量,各国已编制了不少重力坝剖面优化程序,可用电算求解。剖面确定后,再进行分缝、止水、排水、廊道、坝内引水管、深式泄水孔等的设计和计算。对坝基稳定和处理应给予足够重视(见大坝岩基处理)。
