Superplasticity of multi-directional impact forged Mg–Gd–Y-Zr alloy
Journal of Alloys and Compounds, 2016Abstract A novel multi-directional impact forging (MDIF) process was successfully applied to a Mg–Gd–Y-Zr alloy and the superplasticity of the MDIFed alloy was investigated. It was shown that the initial microstructure after MDIF had a unique characteristic of coarse grains decorated by profuse tension twins. Tensile tests at various temperatures and

Abstract Annealing processes in copper, processed by multi-directional forging to strains of ɛ = 0.4–6.0 at 300 K, were studied at 503–573 K. Strain-induced ultrafine-grained copper shows mainly grain coarsening behaviour, which is categorized in three stages, i.e.

Nano-grain evolution in austenitic stainless steel during multi-directional forging
Materials Science and Engineering: A, 2011Abstract Nano-grain evolution in an austenitic stainless steel (SUS 316) during multidirectional forging (MDF) was investigated at temperatures of 77 K and 300 K. The flow stress during MDF and the room-temperature hardness increased significantly with increasing cumulative strain.

To forge a flashless crankshaft within few steps and with low energy consumption innovative forging processes are necessary, such as cross wedge rolling and multi-directional forging. The direct combination of the two forming processes normally leads to flash at the bottom of the crankweb preform after the multi-directional forging.
