Two kinds of ferrite were produced due to slow cooling after intercritical annealing, one being intercritically-annealed (αa phase), and the other transformed (αc phase). The effects distributions αa αc phases on mechanical properties a Fe–0.17C–1.5Si–1.7Mn dual-phase steel examined experimentally at room temperature. types annealing (IA) conducted control distribution.

A novel double-step intercritical annealing (DSIA) process was conducted on Fe-0.16C-4.7Mn-1.6Al-0.2Si transformation induced plasticity (TRIP) steel. In a present study, an effect of different heating and cooling rates applied to the second (IA) step microstructure studied in detail by using scanning electron microscopy (SEM), backscatter diffraction (EBSD) transmission (TEM) techniques. The q...

A new process combining 4% prestrain, intercritical annealing, quenching, and partitioning (prestrain–IA–Q&P) is used to investigate the effect of tensile number on microstructure mechanical properties medium‐manganese steels. microstructural model built based specimens’ properties. The amount tiny brilliant white carbide particles precipitated in seems grow with stretches. test steel's str...

Abstract The development of superior mechanical properties in medium-Mn requires the optimization microstructural parameters such as retained austenite (RA) stability, volume fraction, and morphology. present work explores possibility using a continuous annealing approach instead conventional batch to perform an intercritical (IA) treatment hot-rolled strip Al-alloyed 5Mn steel. Dilatometric st...

MSU: monosodium urate ULT: urate-lowering therapy INTRODUCTION The natural history of gout includes 4 progressive stages (asymptomatic hyperuricemia, acute arthritic attacks, intercritical gout, and chronic gouty arthritis). Asymptomatic hyperuricemia is characterized by elevated serum urate. Deposition of monosodium urate (MSU) crystals in articular and periarticular tissues then instigates ac...

The growth kinetics of ferrite during intercritical annealing steel has been investigated using in situ high energy X-ray diffraction with a specially designed furnace allowing highly quantitative measurements phase volume fractions. Kinetics have obtained at 730?C, 750?C and 775?C different ternary Fe-C-X (where X : Mn, Ni, Mo Cr) alloys quaternary Fe-C-1Mn-1Cr (wt.%) alloy. results were compa...
