Abstract
The complex geometry of thread and difficult access to the thread surface make conventional methods for residual stress measurement impossible. Therefore, an in situ measurement of electrothermomechanical properties of quenched-tempered martensitic pipe steel P110 based on the four-point method was developed in this research. Electrical resistivity and thermomechanical properties of investigated pipe steel P110 due to plastic deformation were determined. The average value of the temperature change, the plastic work per volume, the relative resistance and the relative resistivity of samples up to 3% uniform plastic strain were obtained as 2.2 °C, 30.01 MPa, 0.1 and 0.01, respectively.
