High Strength and Ductility in Multi-Directional Forged Wrought Aluminum Alloys
Advanced Materials Research, 2014A wrought aluminum alloy 3004 was processed by multi-directional forging (MF), natural aging and artificial aging. The samples possess high strength and high ductility after processing. Grain size in samples was reduced evidently. The strength of samples was enhanced by dispersing ultrafine precipitate particles within the grains, reducing grain-size ...

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.

Mechanical Properties of Multi-Directional Forged Al-7Si-4Zn-3Cu Alloy
Defect and Diffusion Forum, 2018In this study, Al-7Si-4Zn-3Cu alloy was processed by multi-directional forging (MDF) at 3, 6 and pass corresponding one, two and three cycle, respectively. The structural and mechanical properties of the alloys were investigated at as-cast, homogenised and MDF states.

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

Superplasticity of fine-grained Mg–xGd alloys processed by multi-directional forging
Materials Science and Engineering: A, 2019Abstract Microstructural development and superplastic behavior of Mg–xGd (x = 1, 2, 3 wt%) alloys were investigated after the multi-directional forging (MDF) process. Microstructural observations of the extruded materials revealed non-homogeneous structures with bimodal grain sizes, consisting of coarse elongated grains resulting from deformation ...

Formation and Microstructure of Ultrafine-Grained Titanium Processed by Multi-Directional Forging
Journal of Materials Engineering and Performance, 2016Ultrafine-grained titanium with uniform grain size for medical applications is obtained by multi-directional forging at 773 K in air. The microstructures and microtextures in the deformed titanium specimens are investigated by optical microscopy, electron backscattered diffraction technique, and transmission electron microscopy.
