摘要： A dislocation density of as high as 1017 /m2 in a tin strip, as revealed by high resolution transmission electron microscope, was induced by current stressing at 6.5 x 103 A/ cm2. The dislocations exist in terms of dislocation line, dislocation loop, and dislocation aggregates. Electron Backscattered Diffraction images reflect that the high dislocation density induced the formation of low deflection angle subgrains, high deflection angle Widmanstätten grains, and recrystallization. The recrystallization gave rise to grain refining. 出版者： Melville: American Institute of Physics 出版日期： 2015-12-01 出處： AIP advances, 2015-12, Vol.5 (12), p.127210-127210-6 資源來源： Directory of Open Access Journals 版權： 2015 Author(s).
