Abstract : Strengthening was the prime objective, but retention of useable room temperature ductility and good resistance to atmospheric contamination were important considerations in the formulation of a balanced alloy. In addition to alloying, these techniques for improving the strength of the chromium were employed: (1) the use of prealloyed Cr-5 Cb and Cr-10 Ta powders, (2) very fine French chromium, (3) attritor milling to create fine chromium and oxide powders, (4) chemical precipitation of powders containing oxide particles, and (5) electrodeposited powders with entrapped oxide particles.
