Development of microstructures with improved cryogenic toughness through local variations in stress state: Aluminum-lithium alloys.

摘要

Microstructurally-induced changes in the local stress state (triaxial constraint) and their effect on fracture-toughness behavior are examined at ambient and cryogenic temperatures in an Al-Li-Cu-Zr alloy, processed in the form of 12.7 mm-thick ''naturall ...
