Material Problems for High-Temperature, High-Power Space Energy-Conversion Systems.

Abstract

High-temperature, high-power space energy-conversion systems follow an evolutionary path through continually expanding materials frontiers. Exponential growth trends point to requirements for ultimate alloys comprising the most refractory metals and metallide additives. Therefore understanding properties, transport tendencies and interaction characteristics of these ultralloy components is a crucial essentiality. Studies of such thermophysicochemical phenomena and their detailed parametric dependencies and influences for refractory materials receive intensive and extensive support in the USSR and other iron-curtain countries. But all potential users also recognize the generic ductility, embrittlement enigmas of the highest-temperature alloys--and the related implications of recrystallization. This latter category is the research area of concentration for these studies.
