Abstract:

The tensile properties of C.V.D. tungsten in the as-received condition were measured at a strain rate of 0.02min from 800 deg C to 1400 deg C in a helium gas atmosphere Grain growth studies have been completed for isothermal anneals of up to thirty hours at fourteen temperatures between 1290 deg C and 2780 deg C for a tungsten-22 wt. rhenium alloy Efforts to accurately calibrate residual stress determinations using a split ring of tungsten with an internal strain gage were continued and An inverse pole figure was determined for a flat piece of C.V.D. tungsten.
