The heat treatment process is a vital step for manufacturing high-speed railway spring fasteners. In this study, orthogonal experiments were carried out to obtain reliable optimised heat treatment parameters through a streamlined number of experiments. Results revealed that a better comprehensive mechanical performance could be obtained under the following combination of heat treatment parameters: quenching temperature of 850 °C, holding time of 35 min, medium of 12% polyalkylene glycol (PAG) aqueous solution, tempering temperature of 460 °C, and holding time of 60 min. As one of the most im...

For his project titled “Thermomechanical Response and Fatigue Performance of Surface Layers Engineered by Finish Machining,” UK's Julius Schoop is the recipient of the National Science Foundation’s (NSF) prestigious Faculty Early Career Development (CAREER) Award.

The application of Additive Manufacturing in the field of biocompatible material manufacturing has truly been beneficial in increasing the biomechanical performance of the end products, as expanded upon in new research in Polymers.
