Signs of Degradation of Carbide Phases in Chromium-Nickel Cast Iron at the Operating Temperatures of Forming Rolls

Materials Science - We study the causes and signs of degradation of cementite in chromium-nickel cast iron used for the production of massive forming rolls and the specific features of structural...     

Dynamics of cathode spots in an axial magnetic field on the fall of a current pulse in a high-current vacuum arc

The cathode attachment of a high-current vacuum arc on the fall of a current pulse was studied. Contacts generating an axial magnetic field were used. The revealed transformation of the attachment shape near zero current was explained quantitatively in a way that was in satisfactory agreement with experimental results.     

An algorithm for interconnection of RTLS and RLS during object images obtaining

It is proposed an algorithm for interconnection of on-board RLS and RTLS operation in case of objects images observation, allowing to increase images resolution and improve of images recognition.     

Combining the process of heat-setting and rewinding polycaproamide yarns

Conclusions The fundamental possibility of preparing heat-set polycaproamide yarns of 4 tex linear density which conform to the requirements of technical conditions has been demonstrated.Heat-set yarns which have been prepared with combination of the heat-setting and rewinding processes have a more uniform shrinkage by package layers than when they are treated with hot water or steam on rigid packages.Combining the processes of heat-setting and rewinding will make it possible to shorten the technological process of manufacturing textile polycaproamide yarns.Translated from Khimicheskie Volokna, No. 3, pp. 43–44, May–June, 1988.
