Copper sleeve improves deformability of steel rods during drawing

Copper sleeve improves deformability of steel rods during drawing

$15.00

Bimetal (steel-copper) rods prepared by explosive welding were drawn from 13 mm to 2.4 mm diameter in 17 draws without intermediate heat treatment. FEM analysis and microstructural observations provided the explanation of the extraordinary deformability which is concerned with a more compressive stress state in the sleeve and steel core surface layer as compared with drawing steel rod without a copper layer. Draw stresses were also determined experimentally and compared with calculated ones. Mechanical properties and surface roughness were also investigated.
