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