A kutatási téma leírása:
The Friction-Assisted Lateral Extrusion Process (FALEP) is a severe plastic deformation (SPD) technique for producing metal sheets from bulk metal or powder, in one single deformation step at room temperature. With FALEP, the microstructure can be highly refined, the grain size can be reduced more than 100 times under an imposed shear strain of 20. The FALEP SPD process is a very promising candidate for industrial applications. There are only very limited studies in FALEP, see the list of papers below.
The candidate will develop an experimental FALEP attachment on an existing high capacity SPD machine in the University of Miskolc to carry out experiments on bulk as well as on initially powder metals. The objective is to obtain sheet metals with nano-size grain structure and a specific shear crystallographic texture. Nano-layered composites will be also developed using the new Accumulative Shear Bonding (ASB) technique. The developed metals will be examined by EBSD; the crystallographic texture by X-ray; material strength, Lankford parameter and ductility by tensile testing. Polycrystal plasticity simulations will be also carried out using the VPSC approach.
The candidate should have good education in mechanics of materials and well informed in metallurgical aspects of material science, with good numerical skills.
