THE EFFECTS OF VARIATIONS IN HEAT TREATMENT ON THE STRENGTH AND TOUGHNESS OF RAIL STEEL

In an effort to develop stronger and tougher rail material, a research program is outlined which was designed to investigate the fundamental metallurgical perameters involved in rail design and manufacture. The first area of study reported here is concerned with the effects of heat treatment variations on mechanical properties of steel, and was planned to determine the feasibility of developing a rail with improved mechanical properties by making only minor variations in the conventional method of processing. A systematic heat-treating schedule was developed to isolate as well as possible, the effects of the different heat-treating parameters. The two main variables studied were austenization temperature and isothermal transformation temperature. Experimentaly, both tensile and impact tests were performed on each of the 14 different heat treatments. Preliminary results are discussed, and the general effects are defined and evaluated.
