[P248] Thermal Activation in Yielding of Single-Crystalline Tungsten
キーワード:Nanoindentation、Tungsten、Plasticity、Thermal Activation、Pop-In
Yielding in sx-tungsten is examined by high-temperature nanoindentation. Main parameters analyzed are hardness and pop-in behavior. Yield stress and strain hardening are estimated via a novel method.
