ABSTRACT
Zinc, mainly used for galvanization or as an addition element in bronzes and brasses presents phase transformations at the solid state. Like any other metallic alloy in the same case, it can be heat-treated which allows for the modification of its properties. Due to the differences in shape, dimension and thickness of zinc-alloy parts, as well as their properties, processes and various applications, only certain cases are subjected to heat-treatments. This article lists the principal zinc alloys concerned before focusing on these treatments, and the implementation of the applications they allow for.

INTRODUCTION
Like all metal alloys that undergo phase transformations in the solid state, zinc alloys can be heat treated to modify some of their properties.
However, given the properties of zinc alloys, the forming process and the applications involved, the heat treatment of zinc alloys is industrially limited to a few special cases.

Zinc alloys and heat treatments
As the heat treatment of zinc alloys is not widely practiced, there is no specific document on this subject. Readers will find below more general sources on zinc alloys, which they can usefully supplement with information available on the various Internet sites cited.
