(Metallurgy) metallurgy a constituent formed in steels by rapid quenching, consisting of a supersaturated solid solution of carbon in iron. It is formed by the breakdown of austenite when the rate of cooling is large enough to prevent pearlite forming

The grains appear to contain microconstituents including martensite (most of the dark features in the HAZ) with allotriomorphic ferrite (shown with arrows) around the prior austenite grain boundaries (dotted line).
With increasing of tempering temperature from 250 to 650oC, the impact energy would increase which is related to the reduction in hardness, martensitic transformation to tempered martensite and consequently ferrite and cementite formation [6, 7, 10].
The high temperature phase is called the austenite phase, the low temperature phase is called the martensite phase.
The collection of 29 papers previously published in journals as far back as 1985 highlights Professor OlsonAEs influential contributions to the understanding of martensite transformations and the development of a systems design approach to materials.
Summary: 18Ni350 Maraging steel samples were martensite aged (maraged) at 480 AdegC for 180 min in a vacuum furnace under pure argon (99.99%) and commercially pure nitrogen gas atmospheres.
Analysis of the sheets welded at this high temperature showed that they contained bainite and were far tougher than sheets welded at room temperature, which contained martensite, a microconstituent with lower yield and tensile strengths than bainite.
The procedure of heat treatment was suggested by steel manufacturer to have proper combination of strength and ductility for the tempered martensite. The average tensile strength and elongation% (in 50 mm) were 635 MPa and 17, respectively.
This is because, when the austenite shears to form the martensite, there are different directions to do this.
In Figure 1(b), EBSD inverse pole figure (IPF) mapping indicates representative fine and homogeneous tempered martensite structure.
