Description
...1..,.: Изобретение относитс к области исгаьиа- , тельной техники, в частности к установкам д}Ц. -исследовани образцов электропровод щих материалов в услови х измен ющейс температуры Известна установка дл испытани образцов материалов при нагреве, содержаща вакуумируемую камеру, размеп1енные в ней захваты и нагреватели ПЬ Известна также установка дл исследований образцов электропровод щих материалов в услови х измен ющейс температуры, вл юща с наиболее блшкрй к изобретению по технической суцщ(х;ти и достигаемому результату, содер5Каща вакуумируемую камеру, размещенные в ней держатели образца и средство нагрева об- i разпд пр мым пропусканием тока . Однако эти установки не обеспечивают точ: ности исследовани из-за защемлени концов образца, так как в образце имеютс предварительные статические напр жени . : Цель изобретени - повышение точности исследовани . Дл этого в предлагаемой установке держате ли выполнены в виде (.-.таканов с жидким проВодником , предназначенным дл размещени в1 нем концов образца. Кроме того, установка может быть снабжена нагревател ми, закрепленными на стаканах, а камера выполнена из электропровод щего материала . . На чертеже изображена установка. Она содержит камеру 1 со щтудером 2 дл ее вакуумировани , держатели , выполненные в виде стаканов 3 и 4 с жидким, проводником 5, например, расплавленным металлом или сплавом (причем стакан 3 выполнен заодно с камерой 1 и вл етс одним из электродов, а стакан 4 вл етс вторым электродом и изолирован от камеры 1 нижней крышкой 6, выполненной из изол ционного материала), средство 7 нагрева образца пр мым пропусканием тока. На стаканах 3 и 4 закреплены нагреватели 8 и 9 в виде спирали. Дл измерени температуры образца предназначена термопара 10. Камера 1 выполнена из электропровод щего материала.

The purpose of the invention is to increase the accuracy of the study. in the form of (.-. takan with a liquid conductor designed to place the ends of the sample in it. In addition, the installation can be equipped with heaters fixed to the cups, and the chamber is made of electrically conductive material. . The drawing shows the installation. It contains a chamber 1 with a shuader 2 for evacuating it, holders made in the form of glasses 3 and 4 with a liquid conductor 5, for example, molten metal or alloy (the glass 3 being integral with chamber 1 and one of the electrodes, and the glass 4 is a second electrode and is isolated from the chamber 1 by a bottom cover 6 made of an insulating material), the means 7 for heating the sample by direct current passing. On glasses 3 and 4, heaters 8 and 9 are fixed in the form of a spiral. A thermocouple 10 is used to measure the temperature of the sample. Chamber 1 is made of electrically conductive material. The installation works as follows. When examining a sample through it passes a current pulse, for example, from a battery
