The influence of quenching on structure and properties nickel-based superalloy EK151-ID FORGINGS

The influence of quenching on structure and properties of high-alloy nickel-based superalloy EK151-ID was investigated. The statistical data of commercial EK151-ID superalloy small-sized GTE disc’s forgings under condition on FSUE «VIAM» was analyzed in this paper. The optimal heat treatment leads to increase of mechanical properties of this alloy was determined.

Effect of carbon fillers on the electrical, mechanical and rheological properties of polyethylene

This article examines the influence of carbon nanotubes (CNTs) and carbon black on the electrical, mechanical, technological and structure of polyethylene. The combination of polymer and carbon fillers produced by melt technology in a twin-screw laboratory. The result was the creation of a composition with a better balance of mechanical and electrical properties.
