Dec 16, 2015 · The increased attention ultrafine grained (UFG) materials have received over the last decade has been inspired by their high strength in combination with a remarkable ductility, which is a DEVELOPMENT OF BULK ULTRAFINE-GRAINED LOW Feb 10, 2018 · The material gets refined to ultra-fine level of average grain size of 0.2 m and the ultimate tensile strength improves from 368 MPa to ultra-high strength of 1008 MPa.
Ultra fine grained steels; Strip casting of steels; Alloy design of steels Effect of grain refinement to 1um on strength and toughness of dual-phase steels 2010-MSE-527-7832 is observed in a novel multi-component (MnSCrAl alloyed) ultrahigh carbon steel during tensile testing at a strain rate of 2x 10^-3 s1 and a temper Acta Facile route to bulk ultrafine-grain steels for high Feb 10, 2021 · The yield strength and ultimate tensile strength properties of ultrafine grained low carbon steel. stability of ultra-fine grained magnesium alloy Fatigue crack propagation behaviour in ultra-fine grained Mar 01, 2005 · The material analysed in this work is an ultra-fine grained low carbon steel (hereafter UFGS). Refining of ferrite grains was carried out by thermo-mechanical treatment applying heavy deformation in the ferrite temperature range by using a hot deformation simulator. The ferrite grain size measured by the lineal intercept method was 1 m.

It is well knownthat the refinement of grainsize inmetals leads toa significant improvement inspecific mechanical properties.Processing sc hedules have beeninvestigatedaimed at producing anhomogeneous ultra-fine ferrite andspheroidisedcarbide aggregate microstructure inultra fine grained steel, UFG steel, carbon, strength, UTS In recent years, a variety of new processing routes has been developed to produce ultrafine grained (UFG) low carbon steels with a ferrite grain size of 1 m and below . UFG DP steels have been produced by applying a two-step processing route consisting of 1) a deformation treatment to produce UFG ferrite and finely dispersed cementite or pearlite and 2) a short intercritical annealing in the
