Microstructural evolution and mechanical behavior of pearlitic steel under multi-directional forging

Journal of Materials Research and Technology
The mechanical behavior and the microstructural evolution of a pearlitic SAE 1080 steel were analyzed along 12 Multi-Directional Forging (MDF) cycles at room temperature and strain amplitude Δε ≈ 0.30 (MDF0.30). The resulting cumulative strain flow curve

Microstructural Evolution in Large-Section Plastic Mould Steel during Multi-Directional Forging

Metals, 2022
To obtain excellent mechanical properties from large cross-sections of plastic mould steel (SDP1), we conducted multi-directional forging (MDF) to control the microstructure of ingots. To investigate the microstructural evolution of SDP1 steel during MDF,

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

Influence of thermomechanical processing on coarse particles, grain structure, and mechanical properties of Al–Cu alloy rings

Journal of Materials Research and Technology, 2023
Rings made of 2219 Al alloy are typically manufactured by multi-directional forging (MDF) and ring rolling at 460 °C, followed by heat treatment. However, this process often results in coarse elongated grains and a large number of coarse Al2Cu particles,

Anomalous Strain Rate Effect in Ultrafine Grained Titanium [PDF]

, 1899
An anomalous effect was found in the strain rate dependence of severe plastic deformed commercially pure titanium with ultrafinegrained structure. A maximum tensile strength was obtained for ϵ˙=10−3s−1. This did not allow a single strain rate sensitivity

Investigation of dry sliding wear properties of multi-directional forged Mg–Zn alloys

Journal of Magnesium and Alloys, 2019
Effect of multi-directional forging (MDF) on wear properties of Mg–Zn alloys (with 2, 4, and 6 wt% Zn) is investigated. Dry sliding wear test was performed using pin on disk machine on MDF processed and homogenized samples.

Microstructures and Mechanical Properties of Pure V and Mo Processed by High-Pressure Torsion [PDF]

, 2009
Two body centered cubic (bcc) metals, V and Mo, were processed by high pressure torsion (HPT) at ambient temperature. Hardness variation as well as microstructural evolution was examined with strain under a pressure of 2 to 6 GPa.
