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 ...

Ultrafine grain development in copper during multidirectional forging at 195 K
Philosophical Magazine Letters, 2007 Strain-induced evolution of ultrafine grains in pure copper was studied in multidirectional forging (MDF) at 195 K. The stress–strain behaviour was characterized by rapid strain hardening during early processing and the rate of strain hardening gradually decreased with straining, leading to an apparent steady-state flow at large cumulative strains of ...
