Polytetrafluoroethylene (PTFE) polymer is used extensively in industry as a solid lubricant
because of its lack of reactivity with most industrial materials. However, PTFE has a low …

Using lightweight systems and friction reduction approaches are two main contributors
towards modern and efficient powertrains in the automotive industry. New materials and …

The present work discusses the influence of friction in metal forming. Experiments were
carried out to determine the coefficient of friction and wear displayed by bearing steel ball …

Equal channel angular pressing (ECAP) is one of the advanced manufacturing methods for
the production of nanostructured samples. The ECAPed materials showed exceptional …

In the present study a new design of the equal channel angular pressing die and punch is
introduced. The new design eliminates the deflection of the punch and at the same time …

The main limitation of the Equal Channel Angular Pressing (ECAP) is the very high required
punching force for pushing the metallic sample to next channel. Frictional forces in ECAP …

Single Step High Pressure Torsion (SIHPT) is a newly developed HPT based method for
processing of materials which is capable of producing nanostructured long samples with …
