ASTM A370 - 11a Standard Test Methods and Definitions for Mechanical Testing of Steel Products
Ductile vs. Brittle Behavior—Body-centered-cubic or ferritic alloys exhibit a significant transition in behavior when impact tested over a range of temperatures. At temperatures above transition, impact specimens fracture by a ductile (usually microvoid coalescence) mechanism, absorbing relatively large amounts of energy. At lower temperatures, they fracture in a brittle (usually ...
