Summary
As a result of tests on porous-iron specimens with porosities of 10, 20, 30, 40, and 50%, sintered for 2 h in hydrogen at 1473°K, stress-strain diagrams were obtained in arbitrary- and true-stress coordinates. Curves of ultimate strength, yield stress, the modulus of elasticity, and the specific work of fracture versus porosity have been plotted.
