Charpy/DBTT measurements help determine what aspect of material aging?

Explanation:
Charpy impact testing is about how aging affects a material’s toughness and the temperature at which it behaves brittly. The test uses a notched specimen struck by a pendulum and measures the energy absorbed until fracture at different temperatures. As materials age, embrittlement mechanisms can reduce toughness and shift the ductile-to-brittle transition temperature higher. So Charpy/DBTT measurements reveal aging-driven changes in ductility and the transition temperature, not electrical conductivity, surface roughness, or thermal conductivity.
