ENSC 3313 THE JOMINY EXPERIMENT FOR HARDENABILITY Lab Experiment 4 (BRING SAFETY GLASSES) INTRODUCTION Steel parts that are used in situations where strength and/or wear resistance is the prime requirement rather than formability and/or weldability, are normally used in a quenched and tempered condition, for example, tools such as chisels, screwdrivers and wrenches; also, connecting rods, piston pins, camshafts, crankshafts, transmission gears, output shafts, ring and pinion gears, axle shafts, and the suspension system on automobiles. In some of these situations, iron castings and surface hardening methods are alternatives. To get martensite initially, the quench from austenite must avoid the nose of the TTT curve. The ease of hardening to martensite is known as the hardenability which is measured by the Jominy test, the object of this experiment. Steels of increased hardenability contain small quantities of Mo, Ni, and/or Cr, in particular, and thick sections can perhaps be hardened fully with relatively mild quenching. The experiment is meant, therefore, to give you an appreciation of steel heat treatment
