Abstract

It is shown that impurity surface-active elements oxygen and sulfur contribute to the formation of misaligned (stray) grains and accelerate the diffusion at interfaces, growth of pores, cracks and coarsening of the hardening γ'-phase. Lanthanum is superior in refining capacity than the other rare-earth metals and magnesium, and the introduction of lanthanum addition allows to obtain ultrapure in the content of oxygen and sulfur alloy ZhS36, and to decrease misaligned grain defect formation. Segregating at interfaces, lanthanum replaces sulfur and decrease interface diffusion and mobility of interface dislocations. It is shown that lanthanum is a highly effective refining, microalloying and modifying addition that increase high temperature strength, cyclic strain life and heat resistance of ZhS36 single crystals. The work was performed with in the scope of complex scientific direction 10.1. realization: «The resourse saved technology of perspective cast and wrought supper alloy melting
