The influences of composite matrix microstructure, reinforcement shape, and processing methodology have been evaluated for a series of near-gamma (Ti 3 Al+TiAl) titanium aluminide matrix composites evaluated in tension and tensile-creep at 800°C. Sp

The influences of atomic ordering and environment on the fatigue crack growth resistance of Ni 2 were investigated. It was found that fatigue crack growth resistance increases with the degree of degree of order. The nearly Ni 2 Cr (degree of order, S

The effects of high fluence fast neutron irradiation on the fatigue behavior, microstructure, swelling, and microhardness were evaluated for annealed Type 304 stainless steel which had attained fluences near 1.6 x 10 2 3 neutrons (n)/cm 2 (> 0.1 MeV)

The microstructure of cold-worked, high-purity nickel has been investigated following ion-simulated irradiation-induced creep with 22-MeV deuterons and 70-MeV α-particles. The irradiations were conducted at 224°C (435°F),at stresses between 170 an

The fatigue and creep-fatigue crack propagation performance of Type 316 stainless steel has been investigated following fast neutron (n) irradiation to fluence levels of 1.5 X 10 2 2 and ∼5 X 10 2 2 n/cm 2 (>0.1 MeV), ∼6 and 26 displacements per

The failure modes and dislocation substructure produced by fatigue crack propagation at 593 C in fast neutron irradiated and unirradiated Type 316 stainless steel were studied. The results indicate that the dislocation substrate produced by the crack

The deformation behavior of CdTe and (Cd,Zn)Te single crystals oriented for single slip has been investigated in the temperature range 200–600 °C. The addition of 4.5 at.% Zn increases the yield strength by about eight times over that of CdTe crys
