TL;DR: The subject of as mentioned in this paper is directed to ferrous-base alloys, particularly to a cobalt-free maraging steel of novel chemistry characterized by a desired combination of strength and toughness, notwithstanding that cobalt is non-essential.

TL;DR: In this article, an eddy current technique was used to determine the volume percent of austenite phase in 18% Ni maraging steel grade 350, which can be applied on the production floor with relative ease compared to the X-ray method.
Abstract: An eddy current technique has been used to determine the volume percent of austenite phase in 18% Ni maraging steel grade 350. The values of volume percent austenite thus obtained are compared with those obtained by an established X-ray diffraction method. The eddy current method has been shown to be very suitable for quick and quantitative determination of austenite phase which can be applied on the production floor with relative ease compared to the X-ray method.

TL;DR: In this paper, a review of the published work on austenite reversion and its effects on properties and performance, covering both base metal and weld joints, is presented, where the authors analyze the impact of the reversion on the performance of the weld joints.
Abstract: In the heat-treated condition, 18% Ni maraging steels have a microstructure of aged martensite and essentially no austenite. However, austenite can form if the material is overaged. This has been termed as austenite reversion, a subject which has received much attention, because it importantly influences properties and performance of the steel. Reversion of austenite in fusion zones of weld joints in these steels has also been widely studied. Because of microsegregation, austenite reversion in the fusion zone is accelerated. Reverted austenite in the fusion zone strongly influences the performance of the weld joints. The present review critically analyses the published work on austenite reversion and its effects on properties and performance, covering both base metal and weld joints.
