Abstract
Способ определения неоднородных участков протяженного изделия из сплава с памятью формы. Использование: для определения однородности протяженного материала изделий, преимущественно проволочного типа, из сплава с памятью формы. Сущность изобретения: способ определения неоднородных участков протяженных изделий из сплава с памятью формы, может быть осуществлен посредством устройства, представленного на фиг. 1. Способ заключается в подаче изделия 6 через устройство 4, в котором оно подвергается охлаждению ниже температуры перехода материала в мартенситное состояние, с измерением термоЭДС проволоки. По изменению термоЭДС определяют участки изделия, в которых область фазовых переходов не соответствует заданной, а значит эти участки отличаются физическими свойствами и подлежат выбраковке. Технический результат: расширение области применения существующих аналогов.The method of determining non-uniform sections of the long products from an alloy with shape memory. Use: to determine the homogeneity of the extended material products, mainly wire type, from an alloy with shape memory. The inventive method for determining non-uniform sections of extended products from an alloy with shape memory, can be carried out by means of the device shown in FIG. 1. The method consists in supplying the product 6 through the device 4, in which it is subjected to cooling below the temperature of the transition of the material to the martensitic state, with the measurement of the thermopower of the wire. According to the change in thermoelectric power, the product areas are determined in which the phase transition area does not correspond to the given one, which means these areas differ in physical properties and are subject to rejection. Technical result: expansion of the scope of existing analogues.
