Superplasticity of a fine-grained Mg–1.5 wt% Gd alloy after severe plastic deformation
The strain rate sensitivity (SRS) of Mg–1.5 wt% Gd processed by conventional extrusion and 2 passes of simple shear extrusion (SSE) was investigated by shear punch testing. Shear punch tests were conducted at initial shear strain rates in the range of 0.003–0.3 s-1 and at temperatures in the range of 573–773 K. A fine-grained microstructure with an average grain size of about 2.5 µm, obtained a...
متن کاملEvolution of texture in an ultrafine and nano grained magnesium alloy
The evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (ABE). The microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°C were characterized. The results showed that after single ABE pass at 100°C an ultrafine/nano grained microstr...
متن کاملDevelopment of an Artificial Neural Network Constitutive Model for Aluminum 7075 Alloy
Development of an accurate neuronal material model for aluminum alloys would facilitate better process control and parameter optimization in the aircraft industry. This research primarily attempts to design a connectionist constitutive model for aluminum 7075 alloy using multi-layer perceptrons. The backpropagation algorithm is used to train the designed network whose performance is then valida...

متن کاملCompositional evolution of Q-phase precipitates in an aluminum alloy
Lightweight, age-hardenable aluminum alloys are attracting increasing attention as a means to reduce vehicle mass and improve fuel economy. To accelerate the adoption of these alloys, knowledge of the complex precipitation processes that underlie their primary strengthening mechanism is essential. Here we employ a combination of atom-probe tomography (APT), differential scanning calorimetry (DS...
