The results of a state-of-the-art survey covering tungsten and ten of its alloys are presented. All data are given in tabular and graphical form covering some of the more important physical, mechanical, and metallurgical properties for each material. References are given at the conclusion of each material section.

The principal reasons which induced the authors to write this book and the features of the book are set forth in the preface to the Russian edition. That section of the science of metals which in Russian is called "metallovedenie" or the "physical chemistry of metals" is generally referred to in scientific and technical literature published in the English language by the term "physical metallurgy." These concepts are much broader than the term" metallography," used in the scientific and technical literature of various countries, and applied solely to research on the interrelationships of the structure and proper ties of metals and alloys. Each science must have its own subject and its own method of research. Certainly, all specialists will agree that metals and alloys, including their solid solutions, mechanical mix tures, and metallic compounds, form the subject of "physical metallurgy" or "physical chemis try of metals." The aim of this science. is to produce a theory and to elucidate the experimental relationships which ought finally to make it possible to calculate quantitatively alloys Of given properties for any working conditions and parameters.

Tensile properties of high purity powder metallurgy tungsten and W-1% ThO2 alloy were determined at various strain rates and temperatures (800-2400 C). 1% ThO2 imparts a slight overall increase in strength properties, although above 0.5 T sub m these properties are affected by void formation. The tensile properties of pure W and W-O.35% Ta single crystals (worked, and worked and recrystallized) investigated from R.T. to 1200C are shown to be affected by C, particularly in the quenched condition. An alloy screening program was conducted with W-25% Re, and 1% ThO2 and 1% HfN additions, and with single crystals of W-3.5% Ta-C. The W-Re alloys have superior strength up to 2400C. A yield stress of 47 kpsi was found at 1600C in the quenched W-3.5% Ta-C single crystal. Reactions between ThO2 and W, C, and several carbides were investigated as was the reaction W+TaC. A phase diagram of the W-Ta-C system resulted.
