EVALUATION OF RMSP TUNGSTEN SHEET.

Abstract

The 0.010-, 0.020-, 0.060-, and 0.100-in. thick Refractory Metals Sheet-Rolling Program (RMSP) tungsten sheets were evaluated by standard accep tance test methods. Chemical analysis, micro structural evaluation, hardness measurements, bend transition studies, and elevated temperature mechanw0 property determinations were performed and the results were recorded for the serialized sheet material. The results obtained during acceptance testing indicated that there were differences between individual sheets within each gage lot of sheet material. These differences could be due to prior processing history, however sufficient data are not available to allow for detailed tracing of each sheet produced. Hot square shearing and hot rotary shearing investi gations were conducted on each of the four gages of RMSP tungsten material. Results of the shearing studies showed that successful shearing could be expected by control of temperature of sheet material, type, and condition of tooling used. (Author)
