Microstructures and mechanical properties of commercial purity iron processed by asymmetric rolling

Plastic instability and strain rate sensitivity of ultrafine-grained iron

“…The microstructures as well as the grain sizes were observed by electron back scatter diffraction (EBSD). The details of the material microstructures and the processing procedures have been given elsewhere [9].…”

Annealing behavior of severely deformed IF steel via the differential speed rolling method

“…The sample after 4-pass of DSR operations showed the highest microhardness value owing to the ultrafine grains and high dislocation density. At temperatures below 773 K, the microhardness value of the annealed samples was reduced due to the rearrangement and annihilation of dislocations [24,25], indicating that static recovery dominated. This result was in good agreement with the previous microstructural observation of the annealed IF steel samples at the same temperatures, in that the ill-defined grain boundaries gradually disappeared whereas the sharp grain boundaries began to appear without any significant change in the grain size.…”

Effect of Asymmetric Rolling on Formability of Pure Aluminium

“…Samples were polished until the middle of the thickness and the Cu Kα radiation were used in these measurements. The acquired data was processed by dedicated software using the MTEX MATLAB tool box 8 . From the processed pole figures, a set of 1000 weighted orientations were extracted and used to compute the <M> value, using VPCS model code developed by Lebenshon and Tome [9][10][11] .…”
