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

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
