A note on the recrystallisation of platinum

Abstract

In a recent paper Professor Ewing and the present author have described phenomena of recrystallisation in a number of metals, such as lead, tin, zinc, and cadmium, at temperatures well below the melting points of those metals. I have recently observed phenomena which appear to me to be of a very similar nature in the case of platinum. It is a well-known fact that a prolonged exposure to a high temperature renders platinum brittle, and that the surface of such platinum, when it has been exposed to flame, shows markings “resembling the appearance of galvanised iron.”
