$Effect of grain refinement on fracture toughness in extruded pure magnesium$

Effect of grain refinement on fracture toughness in extruded pure magnesium

The fracture toughness of extruded pure magnesium increased with grain refinement due to the effect of the plastic zone, which is a sensitive factor related to the mechanical properties of yield strength, elongation-to-failure and strain hardening exponent.
