Chaudhuri, A R; Grant, N J

The accommodation process of fold formation which occurs in the grains when grain boundary sliding takes place has been studied. Specimens of Al, Al-- 20% Zn, and Al--Cu alloys were deformed in creep. The process of deformation was observed either directly during creep or after the specimen had been unloaded. Aluminum--20% Zn specimens were also quenched and aged, and the preferential precipitation occurring on aging was studied in relation to fold formation. (auth)
