57. REDISTRIBUTION OF CARBON AND OXYGEN IN SEMICRYSTALLINE MOLYBDENUM DURING ANNEALING

Author

Abstract

An increase in the annealing temperature of deformed molybdenum containing 0.011% of interstitial elements in the 1150–1550°C interval effects a steady increase in the amount of carbon and oxygen atoms on the grain boundaries as a result of their segregation from the grain body. After annealing above 1350°C (an average grain size d≥30 μm), the process of the outflow of interstitial elements onto the boundaries takes place incompletely, as a result of which a supersaturated solid solution is formed in the grain body. Subsequent annealing at 1150°C for 4 h leads to an additional increase in the oxygen content and to the formation of molybdenum-carbide particles on the boundaries; this causes a small decrease in the strength characteristics, and a sharp decrease in plasticity characteristics.

Abstract

A new coumarin C19H20O5 with mp 78–79° C, [α]D16+213° (c 1.00; chloroform) has been isolated from the roots ofLibanotis schrenkiana, and we have called it libanorin. On the basis of chemical and spectral characteristics, the structure of the β,β-dimethylacrylic ester of zosimol (columbianetin) has been proposed for libanorin.
