The so-called bimodal microstructure of Ti-6Al-4V alloy, composed of primary α grains (αp) and transformed β areas (βtrans), can be regarded as a “dual-phase” structure to some extent, the mechanical properties of which are closely related to the sizes ...

Excess Carbon Enrichment in Austenite During Intercritical Annealing
Metallurgical and Materials Transactions A, 2013Carbon enrichment in the austenite transformed from martensite during intercritical annealing was measured by electron probe microanalyzer and three-dimensional atom probe microscopy in Fe-2Mn-0.3C and Fe-0.35C alloys. At early stages of the transformation, negligible Mn partitioning occurs, and carbon content in austenite is higher than ...

Dilatometric Analysis of Austenite Formation during Intercritical Annealing
Metals and Materials International, 2008Dilatometry is a useful method to investigate the transformation kinetics of ferrous alloys. In the present study, a dilatometric analysis procedure that considers the effect of non-isotropic volume change was applied to evaluate the kinetics of austenite formation during the intercritical annealing of TRIP steels. Metallographic analysis was conducted

Morphology and crystallography of austenite formed during intercritical annealing
Metal Science, 1984AbstractThe formation of austenite during intercritical annealing of ferrite–spheroidized cementite and ferrite–pearlite microstructures in low carbon steels has been investigated. It has been established that austenite which nucleates at a ferrite grain boundary does so with a Kurdjumov–Sachs crystallographic orientation relationship with one or both ...

Simulation of intercritical annealing in low-alloy TRIP steels
Steel Research, 2000A coupled thermodynamic/kinetic calculation of austenite formation during intercritical annealing of low-alloy TRIP steels is presented. The simulation was performed with the use of Dictra computational kinetics software, which employs a procedure for the numerical solution of the coupled diffusion equations involved, as well as mobility databases for ...

Effect of Annealing Temperature on Martensite Start Temperature in Intercritical Region
2015In dual-phase steels, partial austenization may result in different volume amount of austenite depending on intercritical annealing temperature between Ac1 and Ac3 temperatures. The annealing temperature is also responsible of chemical composition and grain size of austenite. This study deals with the effect of intercritical annealing temperature on Ms

Thermodynamic Characterization in Intercritical Annealing Process for Dual-Phases Steels
Advanced Materials Research, 2012The theoretical prediction of chemical composition, the range of main elements and austenite alteration affected by intercritical annealing temperature were conducted by thermodynamic calculations, which agree with the experimental results. When fixing carbon content at 0.1% and calculating temperature at 1000K, to achieve α+γ phases without cementite ...
