METHOD OF DETERMINING IRREGULARITY OF THERMAL EXPANSION COEFFICIENT Russian patent published in 2005 - IPC

Abstract RU 2254567 C1

FIELD: measuring engineering.

SUBSTANCE: method comprises manufacturing articles from various parts of the blanc, measuring their temperature elongation with the use of the interferometric dilatometer, and determining characteristics of irregularity of temperature coefficient of linear expansion. The characteristics of irregularity are determined by comparing the results of measurements for individual objects. The bottom reflecting member of the interferometer is made of the blank to be studied so that it has bearing face, reflecting surface, and height less than that of the blank. The bottom reflecting member and blank bear on the single plane by their bearing faces.

EFFECT: enhanced accuracy.
