Comparison of Grain Growth between Fine-Grained and Coarse Comparison of grain growth of fine-grained and coarse-grained austenite in a Nb-V-Ti microalloyed steel during reheating or equalization at the same temperature was investigated using cold-charging and hot-charging specimens respectively in this study. The results show that the different grain growth behavior appears in fine-grained and coarse-grained austenite. Comparison of Grain Growth between Fine-Grained and Coarse During reheating or equalization, the slow growth rate in fine-grained austenite may be contributed to stronger pinning force of fine precipitates while higher grain growth rate in coarse-grained austenite were believed to the result of lager size difference among part of grains. Grain coarsening occurs in fine-grained austenite as result of precipitate unpinning at extending holding time, but coarse-grained

Controlling the Austenite Grain-Size of Steels Metallurgy

The fine grained steels are thus, able to retain a fine austenite grain size even in long carburising cycles, where the coarse grained steels might coarsen considerably. That is why it is an almost universal use of steel making practice that produces inherently fine grained steels for critical heat treated parts and for alloy steels used for carburising.

If carbon steel plates are supplied as fine grained with aluminum as the grain refiner, you will not develop coarse grains. Aluminum used for grain refinement forms oxides and nitrides that inhibit grain growth during processing.

Fine-Grained Concrete:Significance and Properties

Oct 17, 2020 · Fine-grained concrete, also known as sand concrete, is defined as the concrete in which the coarse aggregate is replaced by sand or any filler material. The maximum size of fine aggregates used in fine-grained concrete is 10 mm. Fine-grained concrete is gaining popularity in modern construction due to the following features:Fine-aggregates are highly manufacturable [] Fine-grain Structural Steel - Katalor SteelFine-grain Structural Steel grades are characterised by a minimum yield strength of 275 - 460 MPa, with good weldability and high resistance to brittle cracking. Fine-grain structural steels are used for manufacturing vessels for pressurised gas, pressure vessels, steam boiler parts, pressure piping, compressors etc. Delivery condition of Fine-grain Structural Steel Grain Size and Its Influence on Materials Propertiesmore dependent on grain size than ten-sile strength [2, 3]. Fine-grain steels do not harden quite as deeply and have less tendency to crack than coarse-grain steels of similar analysis. Also, fine-grain steels have greater fatigue resistance, and a fine grain size promotes a somewhat greater tough-ness and shock resistance. Steels made fine grained by addition of aluminum

In Situ Observations of the Formation of FineGrained

The formation of finegrained mixed microstructure of acicular ferrite and bainite in the simulated coarsegrained heatedaffected zone was investigated by means of in situ observation and EBSD analysis. Single, multiple, and sympathetic nucleation of acicular ferrite were observed. Metallurgy Matters:Making steels strongerFine grain size offers better toughness and ductility. Austenitizing temperatures higher than 1,800 degrees F generally cause a coarse austenitic grain structure, and these coarse-grained steels are usually inferior to fine-grained steels in terms of strength, ductility, and toughness. Normalised fine-grained structural steelsNormalised fine-grained structural steels are traditionally produced by means of heat treatment, so-called "normalising annealing", after rolling. This heat-soaking to above the ferrite-austenite transformation temperature and subsequent slow cooling generates a fine, regular ferritic-pearlitic microstructure in the steel.

Tensile properties and twinning behavior of high manganese

Nov 01, 2008 · On the other hand, in fine-grained TWIP steel, deformation twinning was restricted although the tendency that twins appear when the tensile axis is close to [1 1 1] still remains. When the fine and coarse grains are compared at the same tensile axis between [0 0 1] and [1 1 1], it is clearly found that the grain refinement prohibits twinning.
