Recovery When a strain-hardened metal is heated to a low temperature, the elastic distortions of the crystal lattice are reduced due to the increase in amplitude of thermal oscillation of the atoms.
Webb13 apr. 2024 · Irrespective of the rotation speed, the dynamic recovery and subsequent static recovery, accompanied by sub-grain coarsening and grain growth, predominated in EZ after several thermal cycles and plastic deformation. Grain refinement in EZ was most pronounced at 400 rpm, with an average grain size of about 6.0 ± 3.3 μm. WebbOn this channel you can get education and knowledge for general issues and topics
