Irons hardness

WebSuch an iron, when water-quenched behind the flame or induction coil, a hardness of 35 to 45 HRC may be obtained. The heating temperature, time, amount of dissolved carbon, section-size and the rate of quench controls the microstructure, and thus, the hardness. WebThe hardness test measures the ability of a material to be indented or abraded by another material. In dentistry, microhardess is commonly used due to smaller sample dimensions and multiple compositions of the materials. Two main methods are described in the literature: Vickers and Knoop.

WebAt least four allotropes of iron (differing atom arrangements in the solid) are known, conventionally denoted α, γ, δ, and ε . The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure.
