Abstract

The paper presents the comparative investigation results of phase composition influence of new economically alloying MA20-SP alloy and commercial MA2-1 alloy on their based properties under room and elevated temperatures. It was found out the parameters of bending and deep drawing of sheets. It was showed, that alloying MA20-SP alloy by zirconium and cerium (0,25–0,30 mass %) promotes the forming of high dispersed hardening precipitates of phases, the emergence of uniaxial and refine structure and helps to achieve the higher level of mechanical and technological properties in comparison with MA2-1 alloy.
