Abstract

Distribution of hardness values and plastic deformation in different section of tube drain was analyzed. Deformation charts at cross- sections in bend and after bend zones ware designed. In zone before bending plastic deformation is not more then е = 0,2. In bending zone highest deformation value е ~ 1,0 was fixed in upper part, but in inner and lateral part the values essentially less: е = 0,5—0,7. In after bend zone increasing of plastic deformation these parts of tube up to: е = 0,8—1,2 is observed. TEM experiments demonstrate nanostructure with grain size d = 200 nm. Full text download
