Multidirectional Forging Simulation Research on a Tee Joint Valve [PDF]
Advances in Physics Research, 2014 A numerical tee joint valve model was set up in this paper. The numerical forming simulation was implemented. The load of the upper punch was predicted. The final temperature field shows that varying temperatures are within the feasible forging temperature region. The results from the numerical simulation were verified through the practical experiment.

Multidirectional Forging of High-Leaded Tin Bronze: Effect on Wear Performance [PDF]
Metallography, Microstructure, and Analysis, 2017 The dry sliding wear behavior of high-leaded tin bronze alloy was analyzed after multidirectional forging (MDF). The effect of MDF on the wear performance was analyzed under various loads, sliding velocities, and sliding distances. X-ray diffraction (XRD) analysis and energy-dispersive X-ray spectroscopy (EDS) were carried out on wear surfaces to ...
