Intergranular Cracking

ABSTRACTThis paper deals with the role of charging conditions and strain rate on the embrittlement of several Fe.Al and Fe3Al alloys. Fracture paths are transgranular or mixed mode in both air and after precharging of the iron aluminides, unlike the intergranular cracking typical of Ll2 superlattices exposed to hydrogen. The fractographic observations are consistent with a decohesion mechanism. The role of long range order in transport of hydrogen will be discussed.

Induced Changes

AbstractMany III – V semiconductor alloys exhibit spontaneous (111) alternate monolayer ordering when grown from the vapor phase. We have studied theoretically the ordering induced changes in the optical properties of the semiconductor alloys. We describe (i) the change of the band gap ΔE9, and the valence band splitting ΔE12 as functions of the long range order parameter η, (ii) the consequence of coexistence of (001) epitaxial strain and (111) chemical ordering on the optical properties, (iii) optical anisotropy and spin polarization effects in the ordered alloy, (iv) theory of reflectance-difference spectroscopy in ordered alloy, and (v) the ordering-induced changes on high energy E1 and E2 transitions. Specific, experimentally testable predictions are listed in the summary section.
