The world's output of metals during the period of 1863-1963 was greater than in all the previous years of man's history. In the nineteenth century the only metals available to industry were cast and wrought iron and a few non-ferrous metals and their alloys; by the latter part of the twentieth century, steel and aluminum dominated the world, and metals that were mere laboratory curiosities provided the basis for the technology of nuclear energy and space travel. This book records the extraordinary history of metallurgical progress, in which metal art was replaced by metal science.
