Tailoring Strength and Corrosion Resistance in Al-Zn-Mg-Cu Alloys by Total (Zn + Mg) Content and Multi-Directional Forging Process. [PDF]

Materials (Basel)
The effects of (Zn + Mg) total content (9.6–11.7 wt.%) combined with multi-directional forging (MDF) on the microstructure and properties of high-strength Al–Zn–Mg–Cu alloys were systematically investigated.

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.

Mechanical properties of Al-9Si-0.6Mg-0.1Sr alloy processed by successive hot and cold multi-directional forging [PDF]

, 2023
In this study, the effect of successive hot and cold multi-directional forging (MDF) on the mechanical properties of the Al-9Si-0.6Mg-0.1Sr alloy was explored. The alloy was first homogenized and then forged at 200°C from 3 to 15 passes. After each three

The effect of initial strain in the severe plastic deformation of aluminum on the subsequent work hardening regeneration through low strain amplitude multi-directional forging [PDF]

, 2021
Work hardening caused by Severe Plastic Deformation (SPD) strengthens ductile metals remarkably but practically annihilates their further work hardening during monotonic post-SPD deformation. Low Strain Amplitude Multi-Directional Forging (LSA-MDF) after

Direct Regioselective para‐Fluorination via I(I)/I(III) Catalysis

Angewandte Chemie, EarlyView.
A direct, para‐selective fluorination by I(I)/I(III) catalysis is disclosed that does not require substrate pre‐functionalization. This strategy leverages the Leonard link inherent to phenylpropanoate and phenylpropanamides to promote a spirocyclization/para‐selective sequence. The C3‐side chain maps onto a range of common drug scaffolds and allows the

Refinement mechanism of centimeter-grade coarse grains in as-cast Ti2AlNb-based alloy during multi-directional forging

Materials & Design, 2023
Centimeter-grade coarse grains commonly exist in heavy ingots of Ti2AlNb-based alloy and severely deteriorate their workability. To investigate the refinement of coarse grains, multi-directional isothermal forging (MDIF) was carried out on samples cut ...

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.
