Effect of Heating Rate on Grain Structure and Superplasticity of 7B04 Aluminum Alloy Sheets
Fine-grained 7B04 aluminum alloy sheets were manufactured through thermo-mechanical treatment. The effects of anneal heating rate on grain structure and superplasticity were investigated using electron back scattering diffraction(EBSD) and high ...

Abstract We performed repeated pure shear and equal‐channel angular pressing tests on Fe‐free olivine +10 or 20 vol% diopside aggregates to investigate the characteristics of crystallographic preferential orientation (CPO) development in olivine during diffusion creep.

Superplasticity and anelasticity in fine-grained Sn-Pb alloys [PDF]
Mechanisms which may play a role in superplastic deformation (grain strain mechanisms, grain boundary sliding (GBS) mechanisms) are reviewed. Two well-known lattice dislocation mechanisms are re-evaluated for grain boundary dislocations (GBDs).

This study highlights the drastic influence hydrogen has on the microstructure evolution during severe plastic deformation. High‐pressure torsion of a TiVZrNbHf‐Cu composite results in mechanical alloying and subsequent amorphization, whereas replacing the high entropy alloy with the corresponding hydride stabilizes a two‐phase microstructure.

Effect of Si content on low-temperature superplasticity in Fe–10Mn steel
We systematically investigated the effect of Si on the low-temperature superplasticity of 50% and 80% cold-rolled Fe–10Mn-(0.2–5.5)Si steels through tensile testing at 763 K with strain rates of 1 × 10−3 s−1 and 1 × 10−4 s−1. Superplasticity was achieved

Abstract We analyze large‐scale shear zones that are exposed along the equatorial chasmata of Eastern Aphrodite Terra to understand the role of strain localization in the deformation of the Venusian crust. These shear zones dip at low angles opposite to the slopes, forming terraces that expose portions of the shear planes.

Ultrasonic welding of metals is an energy-efficient, environmentally friendly technology that allows producing solid-state joints between thin blanks. The widespread use of this technology is hampered by the low strength of the resulting joints and the ...

Forming of bulk metallic glasses: ideal superplasticity?
International audienceDue to their brittleness, bulk metallic glasses (BMG) are generally difficult to form at room temperature. A fruitful way to get components is to deform them in their supercooled liquid region (SLR).
