  • How Grain Structure Impacts Steel Strength MetalForming

    Mar 01, 2017 · While true in some cases, the opposite occurs nearly all the time, for it is the microscopic atomic cell (Fig. 1) that can have the biggest impact on steel strength. The atomic cell is the cubic structure that holds the atoms in a neutral condition. If the cube is elongated in one direction, a positive elastic stress results.Read More

  • Understanding Grain Structure and Direction when Plate

    A small or fine grained structure is therefore always stronger than a larger or coarse grained structure of the same metal or alloy. Applying this to metal bending, be it plate bending, press braking or any other type of metal forming, consideration must be given to the grain direction before any process is Read More

  • Hardening of SteelObjectives and Components Metallurgy

    Martensite is the hardest micro structure that can be produced in any carbon steel, but it can be, produced only if the transformation of austenite to mixtures of ferrite and carbide is avoided by faster cooling (quenching) the steel.Read More

  • GRAIN STRUCTURE the warren

    GRAIN STRUCTURE. Metals have a crystalline structure this is not usually visible but can be seen on galvanized lamp posts for example. When a metal solidifies from the molten state, millions of tiny crystals start to grow. The longer the metal takes to cool the larger the crystals grow. These crystals form the grains in the solid metal.Read More

  • Interpretation of the Microstructure of Steels

    Austenite has a cubic close packed crystal structure, also referred to as a face centred cubic structure with an atom at each corner and in the centre of each face of the unit cell. Ferrite has a body centred cubic crystal structure and cementite has an orthorhombic unit cell containing four formula units of Fe 3 C. The phase diagram illustrates the domains in which particular phases or combinations of phases Read More

  • The Metallurgy Of Carbon Steel new

    Cooling of a steel below 0.8% carbon When a steel solidifies it forms austenite. When the temperature falls below the A3 point, grains of ferrite start to form. As more grains of ferrite start to form the remaining austenite becomes richer in carbon.Read More

  • Grain Structure an overview ScienceDirect Topics

    The grain structure of the steel that forms on solidification may turn out to be the same as that seen in the finished casting. However, this would be somewhat unusual. It happens only in those cases in which the metal is a single phase from the freezing point down to room temperature. Examples include some austenitic stainless, and some Read More

  • Austenitic Grain Size of Steel Metallurgy

    As fine grained materials have better room temperature strength, ductility, toughness and other properties, thus, many heat treatments are carried out to obtain fine grain structures. As most of the heat treatment performed on steels alter the grain size, it is essential to control the grain size of steel to achieve better properties.Read More
