Evaluation of Methods to Reduce Hand Straightening of Quenched Aluminum Parts

摘要

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)
