FIGURE 1 STRESS STRAIN CURVE FOR TYPE 3CR12 STEEL FIGURE 2 STRESS-STRAIN CURVE FOR MILD STEEL

Tensile and compression tests were conducted generally in accordance with the procedures outlined by ASTM Standard, A370-77.7 All specimens were tested using an Instron 1195 universal testing machine. Average strain was measured using two strain gauges mounted on either side of the specimen in a full bridge configuration with temperature compensation. Compression test specimens were mounted in a specially

manufactured compression test fixture which prevents overall buckling of the test specimen.
