High-temperature constructional powder steel and alloys

Strong new alloys based on intermetallic Fe-Cr-Al compounds and systems with strengthening by refractory nanoparticles may be used in heat-stressed components of high-speed airplanes and jet engines and in heat exchangers for the oil and atomic industries. Experiments confirm the high performance of such dispersely hardened materials. The small-scale production of hot-deformed components from dispersely hardened high-temperature ferritic ПX25Ю6 + 0.5% Y 2 O 3 steel has been introduced.
