The effect of a service environment exposure on the mechanical properties of a high Nb content TiAl alloy, Gamma MET PX , was assessed. Gamma MET PX, like other TiAl alloys, experiences a reduction of ductility following high temperature exposure. Ex

The authors have reported dislocation densities of cast/extruded and as-annealed NiAl to be typically 10{sup 8} cm-{sup 2}; pressurization to 1,400MPa increased the dislocation density to 10{sup 9} cm-{sup 2} in isolated regions. The representative d

Rapidly solidified samples of CuCr alloys containing 2 wt.% Ag were prepared by high pressure gas atomization and by melt spinning. Both quenching techniques yielded microstructures which showed evidence of the formation of two immiscible liquids

The influence of the ferrite to austenite allotropic transformation on the stability of MXn precipitates in an iron matrix is studied. In the MX phase, M is a group IVb or Vb transition metal, such as niobium, titanium, or vanadium. X is carbon or ni
