Ferrite plate surface is parallel to ferrite {110} and isthe coherent interface for α and γ, the crystallographic relationship is (111)_γ(011)α. Thesmall plate surface of Fe_3C precipitated during tempering is parallel to (100). The strengthen-ing mechanizm for carbon-rich austenite in normalized condition is primarily uniform solid so-lution hardening, however, in the tempered state, it is strengthened chiefly by non-uniform one.
