NANO MATERIALS IMG-20221022-WA00051, IMG-20221022-WA00081, IMG-20221022…

- - - - It is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill.
    - - It is a cost effective and simpler way for producing materials at nano scale level from the bulk materials and also for production of nano composites.
  - - - Equal Channel Angular Pressing (ECAP)
        
        It is one of the severe plastic deformation process to drive nano or ultrafine grained microstructure at low homologous temperature (below 0.3 of the melting temperature)
      - High Pressure Torsion (HPT)
        
        In this process the material is compact under high pressure between two plungers by the way of hydraulic mechanism. It is used for grain refinement.
      - Accumulative Roll Bonding (ARB)
        
        It is a method of rolling a stack of metal sheets, which are repeatedly rolled to a severe reduction ratio, sectioned into two halves, piled again and rolled.
