A Review of Progressive and Compound Forming of Bulk Microparts by Using Sheet Metals

MATEC Web of Conferences, 2018
In the last decade, the concept of progressive microforming has emerged and developed gradually, which is considered as an efficient and promising method to fabricate the micro-scaled part.

Orientational tuning of the Fermi sea of confined electrons at the SrTiO3 (110) and (111) surfaces

, 2014
We report the existence of confined electronic states at the (110) and (111) surfaces of SrTiO3. Using angle-resolved photoemission spectroscopy, we find that the corresponding Fermi surfaces, subband masses, and orbital ordering are different from the ...

Stretching Micro Metal Particles into Uniformly Dispersed and Sized Nanoparticles in Polymer. [PDF]

, 2017
There is a longstanding challenge to disperse metal nanoparticles uniformly in bulk polymers for widespread applications. Conventional scale-down techniques often are only able to shrink larger elements (such as microparticles and microfibers) into micro/

Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

Advanced Engineering Materials, EarlyView.
The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.

Investigation on extrusion processes in sheet-bulk metal forming from coil

CIRP Journal of Manufacturing Science and Technology, 2020
Abstract The increasing demand for functional-integrated lightweight components is bringing established manufacturing technologies to their limits and motivates research into the innovative process class of sheet-bulk metal forming (SBMF). By applying bulk forming operations to sheet metal, thin-walled components with integrated functional elements ...

3D quantum Hall effect of Fermi arcs in topological semimetals

, 2017
The quantum Hall effect is usually observed in 2D systems. We show that the Fermi arcs can give rise to a distinctive 3D quantum Hall effect in topological semimetals.

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

Advanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Manufacturing of hybrid gears by incremental sheet-bulk metal forming

Procedia Manufacturing, 2019
Abstract The weight of automotive components has to be reduced and additionally a higher integration of functions is aspired. In the case of geared components, the incremental sheet-bulk metal forming technology enables the manufacturing of load- and weight-adapted functional parts.
