Ductile deformation - Study guides, Class notes & Summaries

What is the description of damage of a brittle fracture? Sudden rapid fracture under stress (residual or applied) where material exhibits little or no evidence of ductility or plastic deformation What type of Steel are of primary concern with brittle fractures? Carbon and low alloy steels. 400 series SS are also susceptible What has a significant influence on toughness and resistance to brittle fractures? Steel cleanliness and grain size In most cases brittle fractures occur only at what t...
