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 ...

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

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,

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.

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
