Project summary

The Project will be carried out in working premises of the participating institutions - RFNC-VNHTF, Snezhinsk, CRTs, Miass and Institute for Metal Superplasticity Problems of Russian Academy of Sciences, Ufa, located in the territory of Russian Federation.

To develop components of the pilot technology for superplastic forming and diffusion bonding (SPF/DB) of submicrocrystalline (SMC) materials a specialized equipment of the Institute for Metal Superplasticity Problems (IMSP) will be used, in particular, rolling and pressing equipment, specialized facilities for superplastic forming and diffusion bonding based on vacuum furnaces OKB-8086 (work space: diameter is 300 mm and height is 500 mm) and SNVE-1.3.1/16-1 Z-UHLCh. 1.2.3, as well as conventional electrical heaters with protective argon atmosphere. Mechanical testing will be performed on multi-purpose dynamometers made by Instron and Schenck companies, as well as using high temperature vacuum and optical installation ALA-ТОО (IMASH 20-75 type). Microstructure research will be done on optical microscopes Neophot 32, Metaval and scanning electron microscope JSM-840A.
