Conclusions1.Three stages of aging are observed in cast maraging steel Kh14K9N6M5 quenched to martensite and retained austenite. In the first state (up to 550°) martensite decomposes into two solid solutions — ferromagnetic, rich in iron, and nonferromagnetic, rich in chromium, with highly dispersed R phase in the latter. In the second state (550°, 3–50 h) the two solid solutions and R phase that can be detected in powder patterns are retained. In the third stage only the intermetallic R phase… Expand
Phase composition and properties of maraging steels alloyed with molybdenum
Conclusions1.The addition of 2–10% Mo to martensitic steels 13Cr−14Co−6Ni and 9Cr−14Co−6Ni increases the amount of retained austenite. Steels with 13 and 9% Cr become almost completely austeniticExpand
Effect of cobalt and molybdenum on hardening of Cr-Ni stainless steels
Conclusions1.Alloying of Cr-Ni steels with molybdenum (up to 4–5%) leads to additional hardening in the original quenched condition but has almost no effect on hardening during aging of steels notExpand
Phase composition and hardening of steels of the Fe-Cr-Ni-Co-Mo system with martensite-austenite structure
The phase composition and mechanical properties of maraging steels of the Fe-Cr-Ni-Co-Mo system are studied as a function of the alloying and of the temperatures of quenching and aging. TheExpand
Effect of residual austenite and content of hardening elements on the mechanical properties of transition class stainless steels
Conclusions1.The mechanical properties of the transition class stainless steel 03K12N5KM in the quenched condition are determined by its phase composition and do not depend to any significant extentExpand
Effect of alloying and of the austenizing temperature on the phase composition and properties of corrosion-resistant maraging steels
Conclusions1.The optimal molybdenum content of steels based on Fe−0.03% C−12.5% Cr−(0–1)% Ti−(0–12)% Ni−(0–20)% Co is 3%. It is permissible to increase the amount of molybdenum to 5%, but then theExpand
Effect of retained austenite on the properties of cast stainless steels
Conclusions1.Retained austenite from the direct \gg\arM transformation reduces the susceptibility to brittle fracture of cast maraging stainless steels of the Cr\t-Ni\t-Co\t-Mo type; austeniteExpand
