Plastic deformation of a nanostructured and ultra-fine grained Fe-1%Cr with a bimodal grain size distribution
Source abstract
Abstract
The plastic deformation of nanostructured and ultra-fine grained Fe-1%Cr of bulk specimens obtained from mechanically milled iron powder has been investigated by means of compression and tensile tests. The resulting microstructure was related to the mechanical behaviour. It was found that nanocrystalline grained specimens presented strain hardening in compression tests whereas they had brittle behaviour in tensile tests. However, when a bimodal grain size distribution is obtained by heat treatments, an improvement in the strain hardening capacity in both tensile and compression tests was observed.
