Austenitization of FerriticDuctile Iron [PDF]
Archives of Foundry Engineering, 2014 Abstract Austenitization is the first step of heat treatment preceding the isothermal quenching of ductile iron in austempered ductile iron (ADI) manufacturing. Usually, the starting material for the ADI production is ductile iron with more convenient pearlitic matrix.

Quantitative Description of Duplex Stainless Steels Microstructure Using Selective Etching
Metals, 2021 The properties of duplex stainless steels (DSSs) depend on the ferrite–austenite ratio, on the content of secondary phases and on the contamination with non-metallic inclusions. To assess the quality of DSSs, it is necessary to use an integrated approach

Microstructural and Corrosion Properties of Cold Rolled Laser Welded UNS S32750 Duplex Stainless Steel [PDF]
, 2018 The main goal of this work was to study the effect of plastic deformation on weldability of duplex stainless steel (DSS). It is well known that plastic deformation prior to thermal cycles can enhance secondary phase precipitation in DSS which can lead to

Shear-induced α → γ transformation in nanoscale Fe-C composite [PDF]
, 2006 High-resolution transmission electron microscopy and three-dimensional atom probe observations show clearly that a reverse transformation of body-centred cubic ferrite to face-centred cubic austenite occurs during severe plastic deformation of a ...

A theoretical review of the operation of vibratory stress relief with particular reference to the stabilization of large-scale fabrications [PDF]
, 2011 Vibratory stress relief (VSR) is widely used on large welded fabrications to stabilize the structures so that they do not distort during further machining or during operational duty.

Effect of Starting Microstructures on the Reverse Transformation Kinetics in Low-Carbon Steel
Metals, 2020 The effect of the initial starting microstructures on the austenite reverse transformation kinetics is thoroughly studied in low-carbon steel. The different initial starting microstructures including the ferrite + pearlite, bainite, and martensite are ...

Quasiconvexity at the Boundary and the Nucleation of Austenite [PDF]
Archive for Rational Mechanics and Analysis, 2015 Motivated by experimental observations of H. Seiner et al., we study the nucleation of austenite in a single crystal of a CuAlNi shape-memory alloy stabilized as a single variant of martensite. In the experiments the nucleation process was induced by localized heating and it was observed that, regardless of where the localized heating was applied, the ...
