摘要
Abstract
It is proved that the sever plastic deformation is an effective approach to producation of ultrafine grain and nanocrystal ine metal ic materials. Two different deformation methods, namely equal channel angular pressing and rol ing, are used to deform the brass H85 and H90. Through the microstructure observation, effect of pressure on brass plastic deformation mechanism is studied. Results show that twin density increases with increase in pressure, and plasticity and strength can be improved. In addition, lower stacking fault energy can promote twin nucleation earlier and the strengthening ability is improved greatly.关键词
