Preferential alignment of two-dimensional montmorillonite in polyolefin elastomer tube via rotation extrusion featuring biaxial stress field

Composites Science And Technology, 2021
Preferential alignment of two-dimensional (2D) nanofillers in polymer matrix is essential to realize the transition of distinct properties from individual nanofiller into bulk nanocomposites, but this is an impossible task in conventional melt-processing

A multi-objective optimization of energy absorption properties of thin-walled circular tube with combined bar extrusion under quasi-static axial loading: Experiments and numerical simulation

, 2020
Thin-walled tubes are one of the most popular impact absorbers. Recently, some methods have been proposed to improve crush performance parameters of the thin-walled tube such as filling by foam, modifying geometry etc.

Analysis of Superimposed Influence of Double Layer Gas Flow on Gas-Assisted Extrusion of Plastic Micro-Tube

, 2020
A plastic micro-tube is extremely small, and the melt is still in a molten state when the melt exits the die. The inner layer gas still flows in the micro-cavity after leaving the die, therefore, the diameter of the micro-tube increases gradually.

Hydrostatic tube cyclic expansion extrusion (HTCEE) as a new severe plastic deformation method for producing long nanostructured tubes

Journal of Alloys and Compounds, 2019
In the current study, hydrostatic tube cyclic expansion extrusion (HTCEE) was proposed as a new severe plastic deformation (SPD) method for producing relatively long and large ultrafine-grained (UFG) tubes. In this process, a moving mandrel placed inside

Co-extrusion of Zircaloy-2 and Zr-Sn alloy for double clad tube manufacturing: Numerical simulation and experimental validation

Journal of Manufacturing Processes, 2019
Zircaloy-2 cladding in boiling water nuclear reactors is prone to brittle failure due to pellet-cladding interaction (PCI). The simultaneous effects of stress corrosion cracking and cladding stresses are the main failure mechanisms which limit the life ...

Fabrication of bilayer tube consisting of outer aluminum foam tube and inner dense aluminum tube by friction stir back extrusion

Materials Today Communications, 2018
Bilayer tubes consisting of an outer Al-Si-Cu ADC12 foam tube and an inner commercial-purity Al A1070 tube (ADC12 foam/A1070 bilayer tube) with metal bonding between them were fabricated by applying friction stir back extrusion (FSBE).
