<p> Electromagnetic acoustic resonance (EMAR) and magnetic hysteresis loop (MHL) measurements were performed in cast irons with different graphite morphology and matrix structures. The ultrasound transverse velocity, νt proportionally increased with increasing tensile strength in flake graphite cast irons (FC), whereas it was almost constant in spheroidal graphite cast irons (FCD). The coercive force, Hc of MHL was proportional to the tensile strength in FCD with different pearlite fraction in the matrix. The combination of the two techniques utilizes the advantages and compensates for the weaknesses of each technique. Based on the relationship between micro-structures and the physical parameters (νt and Hc), a simple model for estimating tensile strength was proposed. This study demonstrates the feasibility of the combined electromagnetic techniques for the non-destructive evaluation of tensile strength in cast irons.</p>
