SUMMARY

The discussion clarifies the distinction between Ductile to Brittle Transition (DBT) temperature and Glass Transition (Tg) temperature. DBT is primarily observed in crystalline materials, while Tg is associated with amorphous materials. Notably, some materials may exhibit only one of these temperatures based on their structural properties. Additionally, metallic glasses do possess a Glass Transition temperature, despite their unique characteristics.

PREREQUISITES
  • Understanding of material science concepts, specifically Ductile to Brittle Transition (DBT) and Glass Transition (Tg) temperatures.
  • Familiarity with the properties of crystalline and amorphous materials.
  • Knowledge of metallic glasses and their thermal properties.
  • Basic research skills to navigate scientific literature and resources.
NEXT STEPS
  • Research the specific conditions under which materials exhibit Ductile to Brittle Transition (DBT) temperature.
  • Study the mechanisms of Glass Transition (Tg) in various polymer types.
  • Explore the properties and applications of metallic glasses, focusing on their Glass Transition temperature.
  • Investigate the relationship between material structure and thermal properties in both crystalline and amorphous materials.
USEFUL FOR

Material scientists, engineers, and students studying the thermal properties of materials, particularly those interested in the behavior of crystalline and amorphous substances.

Ductile to brittle transition temperature and Glass transition temperature. I know these two are different but don't know in what sense.

Does all the materials have both of these temperatures or only some or none? If only some or none, what property of material will allow it to have only one?
 
Engineering news on Phys.org
Did you try googling this before you asked your question? The first hit on wikipedia addresses this directly.
 
May be you are talking about amorphous materials have Tg and Crystalline materials have DBT, but that does not convince me because, some amorphous polymers have crystalline property too.

And what metallic glasses are?? Don't they have Glass transition temperature?
