When a homogeneous amorphous Pd40.5Ni40.5P19 alloy was subjected to thermal annealing for 30 min at various temperatures, novel microstructures were observed. At an annealing temperature of 603 K, phase separation of the amorphous phase dominated. At 628 K, a precipitation reaction proceeded first. After its completion, a eutectic growth set in. At 638 K, metastable spinodal decomposition occurred first, followed by a eutectic growth. Finally at 673 K, crystal growth of crystalline spinodal network was fast enough to compete with a eutectic growth.

Transmission electron microscopy has been used to study the thermal annealing of radiation induced defect clusters in polycrystalline tungsten. Specimens were taken from cylindrical tensile bars which had been irradiated to a fast (E > 1 MeV) neutron fluence of 4.2 × 1019 n/cm2 at 70°C, annealed for one hour at various temperatures in argon, and tensile tested at 240°C in helium. Foils from both the unstressed button heads and the reduced areas near the fracture were examined.Figure 1 shows typical microstructures in button head foils. In the unannealed condition, Fig. 1(a), a dispersion of fine dot clusters was present. Annealing at 435°C, Fig. 1(b), produced an apparent slight decrease in cluster concentration, but annealing at 740°C, Fig. 1(C), resulted in a noticeable densification of the clusters. Finally, annealing at 900°C and 1040°C, Figs. 1(d) and (e), caused a definite decrease in cluster concentration and led to the formation of resolvable dislocation loops.
