www.egr.msu.edu27.5 The Jominy end-quench test is designed to indicate which one of the following? (a) cooling rate, (b) ductility, (c) hardenability, (d) hardness, or (e) strength. Answer. (c) The reader might be tempted to select (d) because the Jominy test indicates hardness; however, the reason for measuring hardness in the Jominy test is to measure
Experiment: Heat Treatment - Quenching & Tempering
imechanica.orgHardenability: Jominy End-Quench Test Hardenability refers to the relative ability of a steel to be hardened by the formation of martensite. The curves shown in Figure 3 are Hardenability Curves produced from Jominy End Quench Tests where water is sprayed on the end of a heated steel bar. Note the following:

Hardenability of Steel: the Jominy Test - Materials Education
www.materialseducation.orgmeasures. Hardenability also determines the necessary cooling rate, fast or slow, for martensite formation. The Jominy End-Quench test determines hardenability of any variety of steel, and is straightforward due to its simplicity and minimization of variables. The size and shape of
