A principle for producing metastable austenite and controlling its amount and stability in the development of rationally alloyed alloys and strengthening treatments

Abstract

It is known that martensite can form from austenite in deformation. This has been widely used in strengthening treatment of austenitic steels in the stage of preparing final products. Alhough many publications are devoted to the investigation of metastable austenite, they concern mostly the improvement of the properties of metastable austenitic steels. This article shows the possibility of improving the properties of steels and cast irons of other structural classes by forming a structure of metastable austenite in them. A principle is suggested for the development of new steels on the basis of metastable austenite.
