Conclusions 1. For alloys in the recrystallized condition with an increase in rhenium content from 7 to 36% there is an increase in strength and ductility at normal temperature. For metal in the worked condition with an increase in ultimate strength the ductility is almost unchanged. 2. For alloys of molybdenum containing 0.2-7% Re the concentration dependence of mechanical properties at normal temperature changes in another way; in alloy with 4-6% Re in the recrystallized condition there is a sharp increase in ductility. 3. Small additions of rhenium (0.2-0.5%) have the most effect on the level of strength at high (1000-1800°C) temperatures, which is apparently connected with an increase in recrystallization temperature. The effect of an increase in strength with an increase in rhenium content to 36% is lower, the higher the test temperature. At 1800°C the strength of alloys containing from 4 to 36% Re is not higher than the strenth of alloys with 0.2-0.5% Re.
