Ductile-brittle transition of polycrystalline iron and iron-chromium alloys

Abstract:

Fracture toughness of polycrystalline Fe, Fe-3%Cr and Fe-9%Cr was measured by four-point bending of pre-cracked specimens at temperatures between 77 K and 150 K and strain rates between 4.46 × 10-4 and 2.23 × 10-2 s-1. For all materials, fracture behaviour changed with increasing temperature from brittle to ductile at a distinct brittle-ductile transition temperature (Tc), which increased with increasing strain rate. At low strain rates, an Arrhenius relation was found between Tc and strain r...
