This presentation will overview an approach to engineer interphase boundaries in metallic composites to achieve superior resistance to void swelling and helium bubble hardening. Model composite systems of face-centered-cubic (Cu) and body-centered-cubic (Nb, Mo or V) metals are used to elucidate the effects of boundary structure and spacing on the damage accumulation and mechanical properties after helium ion implantation. Transmission electron microscopy (TEM) and nano-mechanical testing are used to characterize the irradiation response. The hardening is correlated with the density of helium bubbles that scales with the density of misfit dislocation intersections at the interface.
||Planned: Stand-alone book in which only your symposium’s papers would appear (indicate title in comments section below)
