microstructural analysis revealed presence of ferrite, cementite, and

martensite/retained austenite constituent phases. The Young's modulus, yield strength,

and ultimate tensile strength were found to be 196 GPa, 707 MPa and 792 MPa,

respectively. The total elongation and uniform elongation values were 15.3% and

revealed ductile fracture of the alloy. Using DIC, a continuous increase in longitudinal ᇏݓࣁඋ࿐߶
