Abstract Dynamic transformation in a 9% Cr steel is shown to improve the room-temperature workability through microstructural modification. The dynamically transformed microstructure contains 10–18% of ductile ferrite brittle martensitic matrix. two-phase results 40% higher uniform elongation and 25% lower tensile strength, which facilitate cold working. Further, presence increase strain hardening exponent, further enhancing workability. It also that dynamic alters matrix, creates secondary...
Dynamic recrystallization (DRX) in 316LN austenitic stainless steel with 0.14wt% nitrogen has been studied using hot isothermal compression tests carried out temperature range 1073-1423K and strain rate 0.001 - 10 s -1 . Critical stress for DRX characterized experimental data. Analysis of results shows that the entire domain critical is directly proportional to peak stress. However, no clear relationship between ε c p prevails over tested domain. Recrystallized grains are quantified by GOS...
The successful manufacturing of SS 316LN components for strategic sectors needs a thorough understanding deformation behavior including mechanical response, relevant microstructural evolution and associated instabilities in both cold hot working domains. This work gives holistic view these aspects using experimental results obtained from plastic the under compressive shear loading. indicate that any temperature can be chosen if strain rates are below 1s-1. At higher rates, steel becomes...
Abstract The conventional manufacturing route for austenitic steels involves casting, ingot breakdown, subsequent hot working, and finally cold with numerous intermediate heat treatment stages. In this study, the potential of warm working to substitute some steps process is examined. A low-carbon stainless steel, SS304L, subjected cold, warm, deformation in light recent understanding working. response these two regimes compared on basis metallurgical, mechanical, variables. Metallurgical...
In this paper, microstructural evolution of Indian Fast Reactor Advanced Clad (IFAC-1) steel during thermo-mechanical processing has been investigated. Hot isothermal forging simulated in a Gleeble® simulator the temperature range 1173-1473K and true strain rate 0.01-100s -1 . Instability map developed using stress-strain data obtained. Effect major parameters on various features studied quantitatively. Results from study have used to construct maps (‘μ-maps’) representing different aspects...
Abstract The phenomenon of dynamic recrystallization (DRX) is central to the hot working and thermomechanical processing austenitic stainless steel. This study aims relate two distinct parameters that influence DRX: content interstitial atoms, such as nitrogen, character grain boundaries in 316LN steel has been subjected at 1,423 K through uniaxial compression different strain rates. At these, microstructure fully recrystallized. nature, character, growth DRX grains are studied using...
Work hardening, dynamic recovery and recrystallization (DRX) occurring during hot working of austenitic steel have been extensively studied. Various empirical models describe the nature effects these phenomena in a typical framework. However, model is sometimes violated following atypical transitions deformation mechanisms material. To ascertain transitions, researchers intentionally introduced discontinuities process, such as interrupting multi-step rolling abruptly changing rate...
