Abstract
ALTHOUGH the definite compounds which iron forms with other elements comprise the subject-matter of vol. A on iron, many elements play such important parts in the chemistry of steel and cast-iron that it has been found advisable to deal separately with such associations of iron and non-metals as can conveniently be termed alloys. This plan has involved very little overlapping. For example, whereas iron carbonyls are properly included amongst the compounds, iron carbide will be found in the present volume on account of its peculiar significance in relation to cast-iron and steel, and we find the phase-systems iron-sulphur, iron-selenium, iron-tellurium, iron-boron and iron-carbon successively described and illustrated with diagrams. Naturally greatest importance is attached to the last-named system. The iron-carbon diagram is set forth very clearly in the familiar compact form, but it has also been enlarged to cover two full pages in order to show the varying readings, sometimes amounting to more than 100° C., of numerous investigators. This is followed by several pages of explanatory notes and references to the literature, so that an enormous amount of significant detail upon this very important and complex problem has been assembled in a fashion that should be invaluable to specialists. The properties of iron carbide, which is so conspicuous a component of these mixtures, are then recorded in great detail in order to prepare the ground for the remaining sections, which deal with problems of solidification and crystallisation of molten steels and with special processes such as annealing, de-carburisation, rolling, hardening, tempering and case-hardening.
