Thermophysical properties of metal melts and problems of nuclear technology

Prokhorenko V., Pazdriy I.

Archiwum Odlewnictwa

2003

R. 3, nr 7

17-24

Expediency of using metal melts as functional materials in technological processes and apparatus of nuclear technology is due to the fact that they, preserving the advantages of crystal metals (first of all, their high thermal conductivity, electrical conductivity and heat capacity), acquire new useful properties because of their fluidity. The loss of strength is not a disadvantage in new conditions of application. At the same time, such properties as convectional heat exchange and radiation-resistant structure make metal melts indispensable for being used as heat carriers of nuclear reactors. At present gallium-based and lithium-based melts are becoming more and more widely used. The article presents the results of such melts studies.

Przeanalizowano perspektywy wykorzystania metali ciekłych jako materiałów do wykonywania czujników temperatury i nośników ciepła w energetyce jądrowej. Przedstawiono wyniki badań właściwości fizycznych stopów galu i litu w zakresie topnienia i krystalizacji.

Influence of environments on materials deformation and fracture.

Panasyuk V.

Prace Naukowe Instytutu Materiałoznawstwa i Mechaniki Technicznej Politechniki Wrocławskiej. Konferencje

1998

Vol. 60, nr 8

55-90

The advances and tendencies in the development of investigations in physicochemical mechanics of materials are considered in the lecture. Principal regulations of the science of environment influence on the processes of materials deformation and fracture and on their crack growth resistance and strength are formulated, solutions of some applied problems are also given.
