Rapid Dissolution of Secondary Phase in Cold-Rolling Al-Cu-Mg Alloy by Electropulsing Treatment
TL;DR: In this paper, rapid dissolution of secondary phase in cold-rolling Al-Cu-Mg alloy was achieved by coupling treatment of thermal field and pulsed electric current, which significantly improves the dissolving rate and decreases the energy consumption.

Adiabatic Shear Localization and Microstructure in Ultrafine Grained Aluminum Alloy at Cryogenic Temperature
TL;DR: In this paper, the effects of temperature and strain on adiabatic shear localization in the ultrafine grained 6061 aluminum alloy under the controlled shock loading experiments were investigated by optical microscopy and transmission electron microscopy.

Microstructure evolution and strengthening mechanism of A356 composites reinforced with micron and nano SiCp
TL;DR: In this paper , dual-scale SiCp/A356 composites with different volume fractions were prepared using the combination of powder metallurgy and hot extrusion, and the effect of different volume fraction on the microstructure and mechanical properties of A356 composite were studied.

Enhancing strength via nano-lattice defects in La0.008Al0.08FeCoCrNiMn high-entropy alloy produced by rapid solidification, cold rolling and annealing
TL;DR: In this paper , the strength and hardness of the La0.008Al0.08FeCoCrNiMn high entropy alloys were first increased and then decreased during the annealing process due to the competitive mechanism between recrystallization softening and precipitated phase hardening.

X-ray line broadening from filed aluminium and wolfram
G.K Williamson,W.H Hall +1 more
TL;DR: In this paper, the authors used a Geiger counter spectrometer to measure the changes in intensity distribution in the spectra of cold worked aluminium and wolfram and found that the line breadths may be attributed to simultaneous small particle size and strain broadening, the latter predominating at the higher Bragg angles.

ImageJ for microscopy
TL;DR: The near-comprehensive range of import filters that allow easy access to image and meta-data, a broad suite processing and analysis routine, and enthusiastic support from a friendly mailing list are invaluable for all microscopy labs and facilities-not just those on a budget.
