Non-isothermal Flow of Al-, Co-, and Cu-based Alloys of Different Spatial Configurations or Structural States: Model Establishment and Experiment

Abstract:

The universal generalizing approach for non-isothermal behaviour of different alloys was provided with the novel deformation modelling. Results show that strong correlation can be found between the predicted model and experiment results, which shows accurate estimation of main applied parameters, such as the linear thermal expansion coefficient. Necking contours and critical thickness at corrugation for ribbon and rod specimens can also be calculated. Fractal analysis of corrugation folds (their main size) was conducted for polycrystalline and amorphous ribbon specimens. Structural peculiarities at the plastic deformation stage were investigated.
