Description

Известны способы изучени  микроструктуры мета.ч.шп г. си.ишон мри их иагреваиии и охлажлени 1 с примсиением дл  этой цели вакуумчон камеры и TepNioriap дл  измерени  температуры и исследовани  состо ни  образца, нагреваемого в ат; осфере различных газов.Methods are known for studying the microstructure of meta-hp sp. C. Sych. Mi and their heating and cooling 1 with vacuuming the chamber and TepNioriap for this purpose to measure the temperature and examine the state of the sample heated in at; Osfer various gases.

Отличие 11)ед.лагаемого снособа or р.звестных снособов MHKpoaiia иза металлов и снлавов при нагревании заключаетс  в том, что нспыгуемому образцу придают форму клмна или конуса и нагревают носредством пропускани  через i-icre- э,1ектричос ого тока.The difference of 11) of the unit of the known method of MHKpoaiia of metal and metal from the known method of heating is that the spooled sample is shaped like a klmn or cone and is heated by passing it through i-icre, 1 electric current.

Определение градиента температур вдоль цсс.тедуемого 1 бразцп осуществл етс  дтосредством нескольких термопар, нрнпаиваемых в р де точек вдоль образца.The determination of the temperature gradient along the csc of the specimen 1 section is carried out by means of several thermocouples, mounted at a number of points along the sample.

Техника осуш.еств.КНи  снособа зак;1Ючаегс  в том, ч;о исследуемый образец, на котором имеетс  участок с нолноованно иоверх-ностью Пплнф), нагр.евают до требуе: ой TeNniepaTypbi, ;ронускп  через пст.ч э/кктрический ток.The technique of drying the material of the test method; 1), the test specimen on which there is a section with the ground and the surface Pplnf) is heated up to the required: TeNniepaTypbi,; ronusp through the current / ect. Current .

Количество тепла, выдел емое образцом, определ етс  напр жением на трансформаторе п регулируетс  посредством потеишыл-псгул тора , реостата и т п.The amount of heat emitted by the sample is determined by the voltage on the transformer n and is regulated by means of a power supply circuit, a rheostat, and so on.

С целью изучени  вли ни  на исследуемый металл илн сп.шв рг.зличных агрессивных сред, а дл  вы влени  микроструктуры нрл ВЫСОКИХ температурах (до 1400), образец помещают в разреженпоо нространетво (с разрежением иор дкаЮ ; 10 мм рт .ст.).In order to study the effect on the metal under study or other aggressive media, and to reveal the microstructure at high temperatures (up to 1400), the sample is placed in a rarefied air (with a vacuum of 10 mm Hg).

Д.1  измерени  температуры в О1де,1ьных участках ,-,ца ;ip;nie:Я1От термопары, соединешп-ле с мн.1.111г. ).Dimension 1 of temperature in O1de, 1 plots, -, ca; ip; nie: I1 From a thermocouple, connected to me.1.111g. ).

Придава  образцу форму клина или конуса, получают желаемый градиент температур вдоль длины образца в пределах температур, намеченных дл  изучени .By giving the sample a wedge or cone shape, a desired temperature gradient is obtained along the length of the sample within the temperature range to be studied.

Таким образом, на одном образце может быть изучено состо ние исследуемото металла или сплава при различных температурах.Thus, on one sample, the state of a metal or alloy can be studied at different temperatures.

После нагрева и требуемой выдержки в заданной газовой среде газы удал ют и образец охлаждают в вакууме до заданной температуры.After heating and the required exposure in a given gaseous medium, the gases are removed and the sample is cooled in vacuum to a given temperature.

После охлаждени  микроструктуру образца исследуют под микроскопом . Видимое под микроскопом строение сплава соо1ветствует его структуре, образовавшейс  при нагреве, вы вленной путем травлени  и сохранившейс  благодар  охлаждению в вакууме.After cooling, the microstructure of the sample is examined under a microscope. The structure of the alloy visible under the microscope corresponds to its structure formed during heating, detected by etching and preserved due to cooling in vacuum.
