A multi-response optimization of the multi-directional forging process for aluminium 7075 alloy using grey-based taguchi method

SN Applied Sciences, 2021
The multi-directional forging process of aluminium alloy 7075 (AA 7075) is studied using Deform 3D Version 11.0 simulation software. This process results in grain refinement in the bulk material.

Mechanical behavior and microstructures of aluminum processed by low strain amplitude multi-directional confined forging

Journal of Materials Research and Technology, 2020
Severe Plastic Deformation (SPD) leads to grain refinement and strengthening of metals. Among the many SPD processing methods, Multi-Directional Forging (MDF) is the only one where in-situ material stress–strain curves can be obtained. These are adequate

Application of multi-directional forged titanium for prosthetic crown fabrication by CAD/CAM

Dental Materials Journal, 2021
Titanium are often used as dental materials, pure titanium present low strength and titanium alloy is reported poor biocompatibility, respectively. To overcome the problem, we fabricated high-strength multi-directional forged (MDF) titanium with improved mechanical properties without changing the chemical composition and evaluated its applicability in ...

Tribological Characterization of Commercial Pure Titanium Processed by Multi-Directional Forging [PDF]

Acta Metallurgica Sinica (English Letters), 2019
This work discusses tribological properties of commercial pure (CP) titanium processed by multi-directional forging (MDF) up to six passes at room temperature and 220 °C. For this purpose, wear test was conducted by dry sliding pin-on-disk method on the initial and ultrafine grained samples using different stress magnitudes of 1, 1.5 and 2 MPa.
