STRUCTURAL MATERIALS, METAL SCIENCE

Gavrish S. V., Loguinov V. V. � Skin materials for the high-pressure discharge lamps: fused silica

Basic properties of the most spread material for the discharge lamps shells, i.e. silica glass, are considered, as well as factors, which determine the quartz radiation-optical stability and its relationship to the lamps� operative conditions. Major consideration is given to the quartz doping and to light-absorbing covering application onto the bulb as a lamp envelope spectral transmission correction method.
Key words: silica glass, doping, optical stability, light-absorbing coverings, lamp envelope

BLANK PRODUCTION

Zyuba N. A., Rootsky D. V., Styazhin A. N., Razorenov A. V., Titov K. Ye. � Chemical inhomogeneity influence on the mechanical properties of ingot forged pieces obtained under different crystallization conditions

Research results of the tail shafts metal are covered; the shafts are obtained from steel 55 ingots of mass 39.5 t. The ingots were cast by new and standard techniques. It is shown that carbon liquation heterogeneity on the ends of the long-measuring forged pieces reduced 1.4�2.0 times on the average in the workpieces obtained by innovative technology as compared to the forged piece manufactured by standard technology.
Key words: ingot forged piece, forged components, chemical inhomogeneity, stability of the mechanical properties
