Phosphoric iron of two different phosphorus content, namely P₁ (Fe-0.30P-0.226C), P₂ (Fe-0.11P-.028C) were first prepared by ingot casting route. The ingot were soaked and forged at 1150℃. The microstructures of the phosphoric iron and its relevant mechanical properties such as hardness and tensile properties have been characterized. J-R curves of the material have been determined at room temperature. Fracture behaviour under tearing load has been studied through fracture toughness tests on phosphoric iron using Compact Tension (CT) specimens of Width (W) =50 mm and thickness (B) =12.5mm. J-R curves were obtained from specimens precracked to a/W = 0.5 .The single specimen unloading compliance method have been used for generating J-R curves.
