A maraging steel with 50 mm initial length 6 mm in diameter was tensile tested and the elongation-load data were given in Table. a). From the data given in Table draw the engineering stress-strain, b). draw the true stress-true strain diagrams. c). Estimate the resilience, d). modulus of elasticity of the maraging steel e). Estimate yield strength, f). ultimate tensile strength and g). reduction of area of the tested samples h). Estimate Strain hardening exponent and i). toughness of the steel j). The maraging steel is expected to withstand an applied force of 50 tones. To assure a sufficient safety, the maximum allowable stress on the rod is limited to 150 kg/mm2. The rod must be at least 1000 mm. long but must deform elastically when the force is applied. Design an appropriate rod. k). Explain the properties, Advantages, Disadvantages and application areas of maraging steels.
