Book excerpt: The effects of boron additions on the physical and mechanical properties of arc-melted tungsten and a tungsten -1 percent tantalum alloy were investigated. Boron additions significantly refined the arc-melted grain size of tungsten. The 1-hour recrystallization temperature was initially increased by small boron additions (approx. 0.01 atomic percent boron), after which it decreased continuously with increasing boron content. High-temperature tensile tests showed that the boron additions produced an initial rapid rise in strength followed by a leveling off of the strength-composition curve. Boron in solid solution was postulated to be the cause of the rapid increase in strength.
