| Abstract: | In order to calculate the modulus of elasticity of the nitrided layer for iron-steel materials,a physical model of composite beam has been proposed.A specimen which was a equal strong beam was used for measuring modulus of elasticity and residual stress of the nitrided layer.The experimental results showed that modulus of elasticity of the nitrided layer was increased 29.2% than matrix and X-ray stress constant K was increased 44.4% than matrix. |
