    Abstract Concurrent heavy ion irradiation during annealing lowered the normal crystallization temperature and altered the type of crystallization reaction in an amorphous 304 stainless steel containing 14 at% tungsten. The crystallization temperature was lower by approximately 150 K during irradation and only a fine grained χ phase was formed during irradiation compared to the dual structure of b c c + χ phase formed in the absence of irradiation. The decrease in the crystallization temperature was attributed to radiation enhanced diffusion and the preferential formation of the χ phase was attributed to localized rearrangement of the amorphous structure due to displacement spikes.

    Notes:
    Abstract The crystallization temperature of amorphous alloys was found to be significantly lowered by heavy ion or electron irradiation during annealing. However, only heavy ion irradiation altered the mode of crystallization. Both a binary and multi-element amorphous alloy showed this type of response to irradiation. Radiation-enhanced diffusion processes in the amorphous state can explain the increased crystallization kinetics during irradiation. Heavy ion irradiation alters the crystallization mode by causing direct transformation to the final equilibrium phase as opposed to intermediate metastable phase formation during thermal annealing or electron irradiation. The equilibrium phase is believed to nucleate directly in the displacement cascades, which only form during heavy ion bombardment.

    Notes:
    Abstract Crystallization in sputter deposited, amorphous FeW and MoCo of μ-phase composition alloys has been studied using transmission electron microscopy (TEM), electrical resistivity and X-ray diffraction. The amorphous alloys exhibit high thermal stability and transform directly to the equilibrium μ-phase with no intermediate metastable phase formation. In FeW, a tungsten-iron solid solution also forms as the alloy composition is actually in a two-phase (μ + solid solution) region. In both alloys, the crystallites form on a very fine scale and the μ-phase is heavily faulted. The crystallization behaviour may be indicative of a marked similarity between the short range structure of the amorphous phase and the μ-phase structure. Changes in electrical resistivity during crystallization are in substantial agreement with the structural changes observed through TEM and X-ray analysis.

    Notes:
    Abstract A crystallization temperature of ∼ 1000 K was observed for an amorphous alloy of MoNi. Recovery of the amorphous matrix prior to crystallization was noted, however. During crystallization, a Mo-rich phase and a Ni-rich phase first precipitated, then reacted to form the equilibrium δ-phase. Exaggerated grain growth or secondary crystallization of the δ-phase occurred upon extensive annealing. This multi-step mechanism contrasts with that in the amorphous μ-phase. The multi-step crystallization process is similar to, though not as complex as, that observed in many liquid-quenched alloys. In particular, no incipient stage of crystallization was noted.
