The bainitic transformation in a Cu-Zn-Al-Mn alloy has been examined with TEM.The re- sults show that the stacking faults and also the bainitic midrib are found at the beginning of bainite formation in the alloy.The stacking fault planes can pass continuously through the midrib in bainite.The growth ledges occur at the broad faces and rims of bainite.The broad and narrow faces of th ledges are parallel to the fault plane and habit plane respectively.Both their Miller indices are {110}_(B2).The moving direction of ledges is parallel to the fault plane. It may be deduced that the bainite in alloy are initially formed by shear and the process of growth are go verned by propagation o f fault planes.
