Effect of Multi-Directional Forging on the Microstructure and Mechanical Properties of β-Solidifying TiAl Alloy [PDF]

Materials, 2019
This study systematically investigated the influence of multi-directional forging (MDF) on the microstructural evolution, hot deformation behavior, and tensile properties of a β-solidifying TiAl alloy. The initial lamellar microstructure of an as-cast alloy was remarkably refined and homogenized by three-step MDF.

Eliminating Anisotropy of 7085 Alloy Forgings via Temperature Combination Control During Two-Stage Multi-Directional Forging [PDF]

Materials
Due to its high mechanical properties and low quench sensitivity, 7085 aluminum alloy is suitable for the aircraft industry. However, large cross-section forgings of 7085 alloy usually have over 40% anisotropy in mechanical behaviors, especially in the vertical direction.

Ductility enhancement of EW75 alloy by multi-directional forging

Journal of Magnesium and Alloys, 2014
AbstractIn this study, the Mg–7Gd–5Y–1Nd–0.5Zr alloy can reach a high ductility by the process of multi-directional forging, and the evolution of the microstructure, texture and the mechanical properties were discussed systematically. The results show that after the solutionized sample was multi-forged at 500 °C, its grain size can be refined from 292 ...

Strength–Ductility Synergy in Biodegradable Mg-Rare Earth Alloy Processed via Multi-Directional Forging [PDF]

Journal of Functional Biomaterials
In this study, a biodegradable Mg-Zn-Nd-Gd alloy was processed via multi-directional forging (MDF) to evaluate its microstructural evolution, mechanical performance, and corrosion behavior. Electron backscattered diffraction (EBSD) analysis was conducted to evaluate the influence of grain size and texture on mechanical strength and corrosion resistance.

Study on fold formation mechanism and process optimization in multi-directional die forged valve bodies [PDF]

PLOS One
Fold defects represent a prevalent and detrimental issue in the multi-directional die forging of complex valve bodies, often resulting in product rejection and increased manufacturing costs. In this study, a three-dimensional thermo-mechanical coupled finite element (FE) model was developed using Forge ®

Textures in Multi-Directional Forged Mg by Neutron Diffraction [PDF]

Advanced Materials Research, 2010
Texture evolution in the MDF processed ZK60 along forging axis was investigated by advanced neutron diffraction. Texture analysis was related to the deformation mechanism. Results showed that basal planes deformation was dominated and accommodated by non-basal and twinning.
