摘要：

An increase in the annealing temperature of deformed molybdenum containing 0. 011% of interstitial elements in the 1150-1550 degree C interval effects an increase in the amount of carbon and oxygen atoms on the grain boundaries as a result of segregation. After annealing above 1350 degree C, the outflow of interstitial elements onto the boundaries takes place incompletely, as a result of which a supersaturated solid solution is formed. Subsequent annealing at 1150 degree C for 4 h leads to an additional increase in oxygen content and the formation of molybdenum carbide particles on the boundaries; this causes a small decrease in strength and a decrease in plasticity.
