Austenite Stability Under Focused Ion Beam Milling
2020Artifacts from FIB milling can be of great concern. Aside from commonly known defects (e.g., Ga ion implantation, re-deposition, microstructure change due to specimen temperature increase, surface amorphization, etc.), FIB milling can even result in phase transformation in some metal alloys.

Stability of Reversed Austenite in 9Ni Steel
Advanced Materials Research, 2012The samples of 9Ni steel were treated by Quenching + Tempering (QT) and Quenching + larmellarizing + Tempering (QLT). The morphology, thermal stability and mechanical stability of the reversed austenite in 9Ni steel were studied by TEM, XRD, EBSD, subzero treatment, three-point bending, uniaxial tension and uniaxial compression.

Creep Mechanisms in Niobium-Stabilized Austenitic Steels
Metal Science Journal, 1968Abstract The steady-state creep rates in the range 550–775° C and 1600–40,000 lb/in2 have been determined for five niobium-stabilized austenitic steels with stacking-fault energies in the range 5–35 ergs/cm2. No effect of stacking-fault energy was observed.

The nature of thermal stabilization of austenite
Metal Science and Heat Treatment, 1972Upon thermal stabilization of austenite the yield stress is increased while the tensile strength remains unchanged. This is associated with the lowering of the MS point. Increasing the incipient shear strength decreases the MS point, in accordance with the requirement for the enhancement of the difference between the free energies of austenite and ...

Mechanical stability and magnetic properties of austenite
Journal of Materials Science, 1995Austenitic alloys have been produced by additional alloying in maraging steel grade 18 Ni at 2400 MPa. The concentration of Mo, Ni and Co was increased individually until the martensite start temperature Ms, was suppressed below ambient value. Charpy impact strength, tensile strength and magnetic properties were determined.

A cyclic austenite reversion treatment for stabilizing austenite in the medium manganese steels
Scripta Materialia, 2017Abstract Tailoring the fraction and stability of retained austenite in the medium manganese steel has always been an issue of great industrial interest. A novel cyclic austenite reversion treatment (ART) is proposed to obtain considerable amount of retained austenite in a Fe-0.21C-4.53Mn (wt%) steel, and it is found to be more efficient by comparison

Fatigue-Characterization of Ti-Stabilized Austenitic Steel
Nondestructive Testing and Evaluation, 1998Abstract The assessment of the actual fatigue damage and thus the remaining lifetime of materials is a subject of enormous scientific and economical relevance. This paper describes investigations for the nondestructive characterization of microstructural changes of the metastable austenitic steel X6 CrNiTi 18 10 (AISI 321∥.

Metallurgist, 2018
Published sources are reviewed devoted to use of heat treatment for high-strength automotive steels based on the phenomenon of carbon redistribution between martensite and untransformed austenite during quenching and partitioning. The possibility of implementing quenching and partitioning heat treatment providing presence of an increased amount of ...
