TLDR
In this paper, the microstructure and mechanical properties of maraging steel 350 were studied after aging at 500 − 650°C and the impact energy, the elongation, and the product of the ultimate strength by elongation were shown to depend on the fraction of reverted austenite.Abstract:
The microstructure and mechanical properties of maraging steel 350 is studied after aging at 500 – 650°C. The yield strength, the ultimate strength, the impact energy, and the hardness of the steel are determined. The volume fraction of reverted austenite after the aging is assessed. The impact energy, the elongation, and the product of the ultimate strength by the elongation are shown to depend on the fraction of reverted austenite in steel 350.read more

Effects of Forging and Heat Treatment on Martensite Lath, Recrystallization and Mechanical Properties Evolution of 18Ni(250) Maraging Steel
TL;DR: In this paper , the microstructural and mechanical properties evolution of 18Ni(250) steel were analyzed, and it was shown that the size of the martensite lath is affected by multiple factors such as the influence of grain size, recrystallization and martensites substructure fraction.

Design of maraging steel with aluminum by laser metal deposition
TL;DR: In this paper , the properties of the samples are represented by field emission scanning electron microscopy (FSEM), hardness measurement, tribological test, and potentiodynamic polarization test, which indicate that these specimens are constituted by massive martensite, slight retained austenite, and intermetallic compounds.
