Splat-Quenching of Zirconium Alloys, with Special Reference to Martensite and Precipitate Reactions.

Abstract

A detailed TEM study is reported of the structure of splat-quenched zirconium alloys as follows: Zr-Nb, various compositions; Zr-27at%Al; Zr-14at%Ni; Zr-24at%Fe. The details of martensite and omega morphology in Zr-Nb, spinodal and precipitation reactions in Zr-Al, and the crystallisation of the amorphous phase in Zr-Ni and Zr-Fe are all fully described. In Zr-FE, a novel morphology is described: a circular core of beta surrounded by six twin-related 'petals' of alpha, forms a 'sunflower' pattern not hitherto reported. (Author)
