Austenite Stabilization of Fe-Ni Alloy
Acta Physica Polonica A, 1994 By X-ray powder diffraction and magnetometric methods we investigated the effect of phase hardening during γ-α-γ transitions. In this case austenite becomes more stable to subsequent γ-α-γ transitions, the dislocation density increases, the grain reduce in fragments and the hardness increases, too.

Formation and stabilization of reverted austenite in supermartensitic stainless steel [PDF]
Metallurgical Research & Technology, 2018 The formation and stabilization of reverted austenite upon inter-critical annealing was investigated in a X4CrNiMo16-5-1 (EN 1.4418) supermartensitic stainless steel by means of scanning electron microscopy, electron backscatter-diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy and dilatometry.

Stability of Expanded Austenite During Annealing in Vacuum
MaterialsIn situ X-ray diffraction has been used to investigate the stability of expanded austenite during annealing in vacuum for the austenitic stainless steel 316Ti, the super-austenitic stainless steel 904L, and the duplex steel 318LN. Expanded austenite has been formed using plasma immersion ion nitriding before.

Stability and mechanical properties of some metastable austenitic steels [PDF]
Metallurgical Transactions, 1972 The relation between austenite stability and the tensile properties, as affected by testing temperature and processing, was studied for a series of alloys of increasing compositional complexity, viz., the Fe-Ni, Fe-Ni-C, and Fe-Ni-Cr-Mn-C systems. The “stress” and “strain induced” modes of transformation to martensite differed significantly in their ...

Mechanical Properties of a Bainitic Steel Producible by Hot Rolling
Archives of Metallurgy and Materials, 2017 A carbide-free bainitic microstructure is suitable for achieving a combination of ultra high strength and high ductility. In this work, a steel containing nominally 0.34C-2Mn-1.5Si-1Cr (wt.%) was produced via industrial hot rolling and laboratory heat ...
