Oxidation behavior of maraging 300 alloy exposed to nitrogen/water vapor atmosphere at 500 °C

Aging heat treatments in maraging steels are fundamental to achieve the excellent mechanical properties required in several industries, i.e., nuclear, automotive, etc. In this research, samples of maraging 300 alloy were aged using a novel procedure that combines different steps with two atmospheres...
