Book Description
Tensile and creep properties to 5000° F were determined for wrought unalloyed tungsten sheet in order to establish design criteria. Three lots of material, prepared in accordance to the same specification, were used. Hardness and tensile values below 2500° F could be correlated for entire lots of material. Correlation was found at strain rate and hold time versus tensile strength properties or elongation values, at certain temperatures. Properties varied with powder lot to such an extent as to affect design parameters.
