Belgorod State University scientists develop a ductile and strong alloy for space industry

According the scientists at Belgorod State University, interviewed by RIA Novosti, the material is cost-effective and can be widely applied in the systems needed for exploration of space, the oceans, the Arctic and the Antarctic. So far the so-called austenitic steels have been used to manufacture systems designed for operation at extremely low temperatures. According to BelSU specialists their strength, ductility and other mechanical properties are often insufficient – for example, for operation in the open space or for creating critical elements for cryogenic equipment.

BelSU scientists have obtained a promising alloy based on iron, cobalt, nickel, chromium and carbon, which they say possess outstanding properties at temperatures down to -150°C and below.

The research results broaden our understanding of the mechanisms determining the behaviour of the TRIP-effect alloys under different conditions. This will enable a more accurate choice of materials and processing technologies to create products with the required set of mechanical properties, the scientists explained.

Further research by the scientific team is aimed at adapting the new alloy to industrial 3D printing technologies.
