The enhanced mechanical properties obtained by refining the grain size down to ultrafine-grained (UFG) regime have attracted considerable attention in recent years. severe plastic deformation (SPD) techniques allow obtaining materials. Different SPD permit processing sheet shape materials such as repetitive corrugation and straightening (RCS) accumulative roll bonding (ARB). In this study, form...

Abstract This study addresses some aspects regarding a computer modelling based on three-dimensional Frontal Cellular Automata (FCA) for the simulation of ultrafine-grained (UFG) microstructure development in purpose-designed microalloyed austenite model alloy i.e. FCC structure. Proposed present is step forward towards understanding deformation and mechanisms occurring during severe plastic (S...

Ultrafine-grained (UFG) metallic materials are at the cutting edge of modern materials science as they exhibit outstanding properties which make them very interesting for prospective structural or functional engineering applications. Due to the progress in severe plastic deformation techniques during the last decade, ultrafine-grained microstructures are no longer only restricted to easy to def...

The task of wear resistance improvement for bearing steels working at high loads in water medium was solved by laser alloying with Sn. The modified zone contains up t o 22 wt.% Sn, which is used as a solid lubricant during exploitation. As a result the bearing race's durability is increased 2.5 times. The combination of laser alloying from a nitrogen jet with surface plastic deformation (SPD) w...

Ternary Mg–Y–Zn alloys have attracted considerable attention due to their excellent mechanical properties and unique microstructures. Microstructural variation and the resulting mechanical properties can be affected by various processing routes, particularly those involving severe plastic deformation of a cast billet. The following approach was used in this work to perform a comparative study: ...

The processing technology of steel structural elements aircraft parts is especially important since, if improperly processed, this material can be subjected to weathering, causing corrosion. Furthermore, special attention paid the walls holes used for bolting. Since become stress concentrators, paper proposes strengthen them by implementing SPD (surface plastic deformation) method. article desc...

Effect of strain energy on corrosion behavior ultrafine-grained (UFG) copper prepared by severe plastic deformation (SPD) was investigated in terms microstructural evolution. The SPD processed material showed an structure after grain refinement for several time processes, which will affect mechanical and Homogeneity can be obtained efficiently through the pressing process commonly known as simp...
