WebThe ductile-to-brittle transition can be measured by impact testing: the impact energy needed for fracture drops suddenly over a relatively narrow temperature range – temperature of the ductile-to-brittle transition. Ductile-to-brittle transition Impact Energy BCC metals (e.g., iron at T < 914ºC) Temperature High strength materials (σy > E/150) WebIn essence, brittle fracture is due to direct bond breaking resulting in cleavage. Ductile fracture is due to microvoid growth and coalescence. Temperature sort of maps to time and information transfer. At high temperatures, particles/dislocations travel quicker and with more ease than at lower temperatures. dahle 155 professional pencil sharpener biocube read write and think
