摘要： Apparatus and process for selectively heat treating at least a portion of an article in the field with autoregulated heating. The autoregulated heating is provided by a heater including at least a first magnetic material disposed along the portion of the article to be heat treated. The first magnetic material has a magnetic permeability which sharply changes at temperatures at or near the autoregulating (AR) temperature thereof. The changes in permeability result in corresponding changes in the skin depth of the first magnetic material and, hence, the heating produced therein responsive to a.c. current passing therethrough. By maintaining the a.c. current constant in amplitude and frequency, the first magnetic material and the portion of the article are regulated at substantially the AR temperature of the first magnetic material. By selecting the first magnetic material to have AR temperature substantially corresponding to the temperature at which metal anneals, tempers, hardens, softens, stress relieves or the like, heat treating at an autoregulated temperature is achieved. The autoregulated heater can be incorporated into the article or can be applied to the article thereafter, in each case permitting in field heat treating. Autoregulated heating can also be achieved by any of various multilayer structures to provide desired autoregulation effects.

摘要翻译：用于使用自动调节加热选择性地热处理场中物品的至少一部分的装置和方法。自动调节加热由加热器提供，所述加热器至少包括沿待热处理的制品的部分设置的第一磁性材料。第一磁性材料具有在其自调节（AR）温度或其附近温度下急剧变化的磁导率。渗透性的变化导致第一磁性材料的皮肤深度的相应变化，并因此导致其响应于直流产生的加热。电流通过。通过维持a.c. 振幅和频率的电流常数，第一磁性材料和制品的部分基本上被调节在第一磁性材料的基本上的AR温度。通过选择第一磁性材料使AR温度基本上对应于金属退火，温度，硬化，软化，应力消除等的温度，实现了在自动调节温度下的热处理。自动调节加热器可以并入到制品中，或者可以随后施加到制品上，每种情况都允许进行现场热处理。也可以通过各种多层结构中的任何一种来实现自动调节加热，以提供期望的自动调节效果。
