BelSU researchers patent a method of chromium-molybdenum alloys machining

Perlitic chromium-molybdenum steels are widely used in various economic sectors including chemical industry, power generation, natural oil and gas production. However, these materials are characterised by a relatively high ductile-brittle transition temperature below which the steels become brittle. Materials hardening by using alloying additives may lead to increasing the alloys costs and limit their application scope.

The team of scientists at BelSU Institute of Materials Science and Innovative Technologies has proposed a solution to this problem by developing a method for steels working that ensures their high strength characteristics in low temperatures.

According to Rustam Kaybyshev, the Director of the Scientific and Research Institute for Material Science and Innovative Technologies, the novel method will enable developing a striple-like structure in chromium-molybdenum steel, which in turn will ensure higher strength properties as well as values of impact toughness in low temperatures.

The invention will allow developing materials adapted to natural and climatic conditions of the Far North, which makes this method of steel working highly demanded in gas and oil production, storage and transportation on the Arctic shelf, as well as for facilities and structures utilized for different purposes in low temperatures.
