The automotive industry has placed significant emphasis on weight reduction to achieve better fuel economy while maintaining safety and quality standards. One way this can be achieved is by using forged magnesium alloys due to their high stiffness- and strength-to-weight ratios.
Development of a Manufacturing Process for High-Power-Density Hollow Shafts, Hao Pang, Research Assistant and Gracious Ngaile, Professor, North Carolina State University, Department of Mechanical and Aerospace Engineering, May 2019 Final Report

This FIERF supported research presents a new method for forging hollow shafts for power transmission. This method consists of three main operations; selective heating of a tubular workpiece, upsetting of the workpiece to produce a solid section in the heated section and, flanging or heading of the hot solid portion of the tubular workpiece. FEA and experiments were carried out to determine the feasibility of the process.
