Abstract. Equal channel angular pressing (ECAP) as a severe plastic deformation (SPD) technique was employed for consolidation of AZ31 magnesium chips. The chips were consolidated at temperature 300 °C following ECAP route A up to two passes. optical and scanning electron micrographs reveal that have taken place the quality improves with number passes hence total imposed strain. Vickers hardnes...

The micro-injection upsetting (MIU) experiments of commercially pure aluminium have been conducted on two groups specimens with different grain structures. One group is coarse (CG, undeformed) and the other fine (FG) achieved via 4th pass equal channel angular pressing in micro-meso/scale. were further processed by micro/meso-scale extrusion before conducting MIU for fabricating tiny pins. Micr...
