Fig. 8. 3D renderings taken from SR-μCT images of an HRAM-processed tensile specimen loaded to (a) 0 MPa, (b) 813 MPa, (c) 862 MPa, and (d) 906 MPa. The sphericity of the defect is defined as π1/3(6 V)2/3/A, where A is the surface area and V is the volume. The equivalent diameter is calculated based on a sphere with the same volume as the defect.
