Evaluation of Residual Stress and Tensile Properties of Railway Axle Using Instrumented Indentation Method

Abstract This paper deals with the characterization of residual stresses railway axle made EA4T steel using instrumented indentation technique (IIT). Additionally, tensile properties were also evaluated by IIT. Moreover, hole drilling method was carried out to measure stress. Multiple comparison tests between conventional methods and IIT out. The obtained results discussed against literature data. Results stress assessed follow same trend are in acceptable agreement. data as follows: YS ≥ 420 MPa UTS ∈ ❬650-800❭MPa which is satisfactory agreement standardized tests.
