Abstract : Two methods of reducing hand straightening time of heat treated sheet aluminum parts were evaluated. No reduction of distortion occurred by quenching aluminum parts in water 'dispersed' by a double screen floor in a standard quench rack. An increase in ductility and subsequent reduction in hand straightening time resulted by reducing the natural aging time of quenched parts. This was accomplished by a rapid post-quench cooling cycle and a reduced handling delay involved in transferring quenched material to the refrigerators. (Author)
