THE FABRICATION OF TUNGSTEN
Technical Report
·
OSTI ID:4212366
The outstanding strength of tungsten is illustrated by a comparison of some of its significant physical properties with those of other metals. The effects produced by heating tungsten are discussed. The most important of these changes is the ductile-brittle transition at about 200 to 400 C, and the effective recrystallization temperature at about 1500 C or above. The consolidation of tungsten by powder-metallurgy procedures and by arc melting is summarized. Considerations of importance in primary working, secondary working, and joining are also summarized.
