Abstract
The importance of the Solid State Processes (SSP) of materials increased in the last decade due to the industry demands of improved properties of joined/surfaced materials, combined with costs reduction and energy saving. In this view, new and/or micro-scale solid state processed materials are used by aerospace, automotive or electrotechnics industry. Nowadays, classic solid state processes are mainly applied to light materials, but progresses were also reported in steels. In this field, the tools design, the technology and practical techniques surpassed the fundamental approach of the materials solid state processing. The SSP parameters evaluation is based on different Finite Element Models, approaching the material flow in the large plastic deformation domain. The materials flow theoretical outputs, as strains and stresses, were experimentally validated as well as the joints quality dependency on the up-setting and/or friction force. The paper approaches the solid state welding/joining and surface processing based on thermo-mechanical energetic input. The envisaged Solid State Processes are: Solid state joining processes as Cold Welding - CW (butt and spot welding); Friction Stir Welding - FSW; and Surface Processing: Friction Stir Processing - FSP. Therefore, the presentation will focus on: the deformation and flow pattern of the parent metal in case CW and FSW/FSP; SSP Finite Element Modelling; processes parameters evaluation and correlation; local analysis of the material¿s structural transformations and hardness measurements.
