摘要

Hardenability is the ability of steel to partially or completely transform from austenite to some fraction of martensite at a given depth below the surface when cooled under a certain condition. The "gold standard" test for all hardenability results has always been the "Jominy End-Quench Test." The information gained from this test is necessary for metallurgists when selecting the proper combination of alloy steel and heat-treatment parameters in order to minimize their thermal stresses and distortion in the manufacture of components of various sizes.
