Findings from Saha Institute of Nuclear Physics in the Area of Applied Physical Science Described (Evolution and interaction of twins, dislocations and stacking faults in rolled alpha-brass during nanostructuring at sub-zero temperature)

By a News Reporter-Staff News Editor at Journal of Physics Research -- Data detailed on Applied Physical Science have been presented. According to news reporting originating in Bengal, India, by VerticalNews journalists, research stated, "The effect of cryorolling (CR) strain at 153 K on the evolution of structural defects and their interaction in alpha-brass (Cu-30 wt.% Zn) during nanostructuring has been evaluated. Even though the lattice strain increases up to 2.1 x 10(-3) at CR strain of 0.6 initially, but it remains constant upon further rolling."

The news reporters obtained a quote from the research from the Saha Institute of Nuclear Physics, "Whereas, the twin density (beta) increases to a maximum value of 5.9 x 10(-3) at a CR strain of 0.7 and reduces to 1.1 x 10(-5) at 0.95. Accumulation of stacking faults (SFs) and lattice disorder at the twin boundaries causes dynamic recrystallization, promotes grain refinement and decreases the twin density by forming subgrains."

According to the news reporters, the research concluded: "Detailed investigations on the formation and interaction of defects have been done through resistivity, positron lifetime and Doppler broadening measurements in order to understand the micro-mechanism of nanostructuring at sub-zero temperatures."
