Изобретение относитс к области количественного металлографического анализа.This invention relates to the field of quantitative metallographic analysis.
Известен способ определени удельной поверхности раздела фаз при помощи телевизионных металлографических анализат оров, при котором количество пересечений строк развертки с границами микроструктуры определ ют на произвольно выбранной длине строк, а ее измерение осуществл ют при помощи объекта -микрометра.A known method for determining the specific surface area of an interfacing using television metallographic analyzers, in which the number of intersections of the scanning lines with the microstructure boundaries is determined at an arbitrarily selected line length, and its measurement is performed using a micrometer object.
Предложенный способ отличаетс от известного тем, что длину строк развертки выбирают не произвольно, а при помощи диафратмировани устанавливают равной одному миллиметру. Это обеспечивает автоматическое определение числа т пересечений строк развертки с границами фаз на 1 мм, необходимое дл измерени удельной поверхности раздела фаз (5уд 2т).The proposed method differs from the known one in that the length of the scanning lines is not chosen arbitrarily, but using diaphragm is set equal to one millimeter. This provides an automatic determination of the number of t intersections of the scanning lines with the phase boundaries of 1 mm, which is necessary for measuring the specific interface (5ud 2t).
В качестве устройства дл реализации сиособа используют телевизионные магнитные анализаторы с электр.ической или оптической диа фрагмой. Суммарную длину строк развертки можно устанавливать равной 10 мм, где rt , 2, 3 и т. д.Television magnetic analyzers with an electrical or optical diaphragm are used as a device for implementing the siooba. The total length of the scan lines can be set to 10 mm, where rt, 2, 3, etc.
Предмет изобретени Subject invention
Способ определени удельной поверхности раздела фаз при помощи телевизионного металлографического анализатора, при котором определ ют количество пересечений строк развертки с границами раздела, от.шчающийс тем, что, с целью интенсификации процесса определени , подсчет количества пересечений строк развертки с границами раздела производ т на суммарной длине строк, равной 1 мм.The method of determining the specific surface area of the phase using a metallographic television analyzer, in which the number of intersections of the scanning lines with interfaces is determined, which, in order to intensify the determination process, count the number of intersections of the scanning lines with interfaces made on the total length rows equal to 1 mm.
