THE DEVELOPMENT OF FABRICATING TECHNIQUES FOR PRODUCING HIGH PURITY RHENIUM STRIP 6 BY 6 BY 0.005 INCHES

Abstract

The uccessful fabrication of an electron beam melted ingot and pressed and sintered bar of high purity Rhenium to thin gauge sheet is discussed. The effect of annealing conditions, worki g temperature, and other fabricating variables on the quality of finished sheet is reported. The most successful method of conversion was cold rolling of press d and sintered bars with intermediate process anneals in di sociated ammonia (3 parts hydrog 1 part nitrog n). This proc dure r sulted in thin gauge sheet of higher puri y than material processed from electron beam melted ingots. (Author)
