Prerequisite for nanocrystallization are high nucleation rates combined with slow growth. The resulting mean (quasi)crystal diameter in so-called bulk Zr-based metallic glasses was observed to decrease with the annealing temperature. In a typical met

Glassy Zr–Cu–Ni–Al precursor alloys exhibit quasicrystal forming ability in a narrow concentration range via isothermal heating. The formation of quasicrystals has been explained by various arguments. Often, they are considered as Hume-Rothery

Zr–Cu–Ni–Al alloys belong to the best glass forming systems known. Zr 68.5 Cu 13 Ni 11 Al 7.5 metallic glasses [1] are known to transform by primary crystallization into a quasicrystalline structure. Since small Hf-addition were found to stabil

Nanocrystalline materials can be produced e.g. by high energy ball milling or vacuum condensation; these methods require powder compaction as a final step. In another route - the nano-crystallization - metallic glasses are used as precursors for nano

Zr-Cu-Ni-Al exhibits one of the best glass forming alloys known. In a narrow concentration range, however, annealing leads to the formation of a metastable icosahedral phase. The aim of this paper is to investigate in detail the influence of alloying
