Deformation behavior of Mo 5 Si 3 was studied using single crystals under compression. It was found that yielding and flow behavior were strongly dependent on temperature, strain rate and crystal orientation. A stress exponent and an activation entha

This paper presents an investigation into the development of a rugged, low cost, point infrared sensor to monitor and control the welding process in harsh fabrication environments. Perturbations occurring during the welding process create changes in

Currently available shape memory alloys (NiTi, CuAlNi, CuSnAl) lack the high transformation temperatures and long term thermal stability desired in many commercial applications. This paper reports the results of an investigation in which Pd was subst

Creep behavior of molybdenum-based alloy single crystals at an elevated temperature (∼0.6Tm) was examined in this study. Grain boundary sliding is absent in solution strengthened single crystalline alloys, resulting in significantly reduced creep r

The intrinsic ductility of FeAl (in ultrahigh vacuum) decreases with increasing Al content, from around 16% in Fe–37Al to zero in Fe–48Al. The sharpest decline occurs around the composition where the fracture mode changes from transgranular to in

This is a reply to Schulson`s comment on the authors` recently published paper. Schulson makes three points in his paper: (a) grain boundaries in Ni-rich Ni{sub 3}Al are enriched in Ni, whereas those in stoichiometric Ni{sub 3}Al are not; (b) boron i
