... that the sample annealed at 500°C have texture components of cube, Goss, rotated-Goss, and Y orientations. These texture components were in relation with the formation of annealing twins and Σ3 boundaries. It was also shown that twin-induced GBCD evolution occurred by strain-induced boundary migration, multiple...

...M. Sabet; A. Zarei-Hanzaki; Sh. Khoddam The twinning-induced plasticity (TWIP) phenomenon is established as the most effective mechanism to enhance the formability of the advanced high-Mn (15–30 wt %) austenitic steels (known as TWIP steels). As the formability is very sensitive to the steel...

... bulging accompanied with twinning takes place. Two polycrystalline coppers with 99.99 and 99.9999 mass percent purity used in the present work are designated as 4N and 6N Cu, respectively. The 4N Cu had an equiaxed grain structure with an average size of 230 μ m . The 6N Cu was continuous-cast...
