Determination of Young Modulus and Stress-Strain Curve for Metal Fe and Interstitial Alloy FeC

In this research, the numerical calculation for elastic and nonlinear strains of Fe metal FeC alloy under different pressures has been performed by statistical moment method SMM with Mie–-Lennard–Jones potential (MLJ) Embedded-Jones Atom Method (EAM). The analysis reveals that an enhancement in concentration (cC) from 0 to 5% causes a decrement Young’s modulus (E) at room temperature (T = 300 K) FeC. These calculated results are consistent experimental results. addition, obtained stress-strain curves perfect agreement curves. Besides, increasing cC continuous strain decreases stress, showing adding C form steel will increase strength hardness, but decrease elasticity hardness. be very useful not only studies also theoretical metals their interstitial alloys.
