Microstructure, crystallographic texture, and stretch- flangeability of hot-rolled multiphase steel

The microstructure, crystallographic texture, strain hardening in the hole edgepunched and stretch-flangeability of hot-rolled multiphase sheet steel is investigated by scanning electron microscopy, electron backscatter diffraction, and microhardness measurements. The results show that the strain ha...
