Effect of Combined Tempering and Aging in the Austenite Reversion, Precipitation, and Tensile Properties of an Additively Manufactured Maraging 300 Steel
(2021-01-01)
Maraging 300 is an ultrahigh strength steel with significant alloy addition, resulting in a martensitic matrix hardened by precipitation through aging treatment. In these steels, intercritical tempering can provide reverted ...
Effect of thermal cycling and aging stages on the microstructure and bending strength of a selective laser melted 300-grade maraging steel
(2019-06-05)
Additive manufacturing techniques allow the creation of complex parts in a layer by layer fashion, bringing new opportunities in terms of applications and properties when compared to conventional manufacturing processes. ...
Austenite reversion kinetics and stability during tempering of an additively manufactured maraging 300 steel
(2019-10-01)
Reverted austenite is a metastable phase that can be used in maraging steels to increase ductility via transformation-induced plasticity or TRIP effect. In the present study, 18Ni maraging steel samples were built by ...
High-temperature creep resistance and effects on the austenite reversion and precipitation of 18 Ni (300) maraging steel
(2015-09-01)
Abstract In this paper, the high-temperature creep resistance and effects on the austenite reversion and the dynamic evolution of precipitates of maraging 300 steel were investigated. The main strengthening mechanism in a ...
Microstructural characterization of joints of maraging 300 steel welded by laser and subjected to plasma nitriding treatment
(2016-01-01)
Amongst the ultra high strength steels, the maraging steels have been noticed because they maintain the fracture toughness superior to other steels of their class. The main difference is the way they acquire resistance. ...
Microstructural Characterization of Maraging 300 Steel Fabricated by Select Laser Melting
(2021-01-01)
3D printing of components using a layer-based deposition of materials is referred to as additive manufacturing (AM). The ability to build complex geometry components, reduce waste and avoid assembly are the main advantages ...
Short-term creep properties and fracture surface of 18 Ni (300) maraging steel plasma nitrided
(2017-01-01)
Plasma nitriding of a solution annealed and aged 300 grade maraging steel was studied aiming to increase the creep resistance. The surface microhardness reached 1,140 HV, producing 50 μm layer composed of ε-Fe3N and γ'-Fe4N ...
