回火

The results show that the life of low cycle large strain fatigue N of nitinol is between 102 -104 cycles; The less the cycle strain, sheet thickness, wire diameter and range of strain angle are, the more the life of fatigue is. Heat treatment of nitinol pl...

结果表明：TiNi合金低周大变形疲劳寿命在102-104之间；板厚、丝径、形变角幅度愈小，寿命愈长；热处理制度对疲劳寿命有重大影响，采用热拉伸工艺和400-500℃回火，合金有较好综合性能；合金中杂质含量和成分组织均匀性对合金性能有着重要作用。

At this point, stressed by the spring wind pressure plate should be flat on the plane of the inlets and seamless.

因为不同的烹饪过程要求不同的火力，这就需要在使用中调节灶具的热负荷，因而要求无论是将火力调大或调小，燃气燃烧都要稳定，不应出现脱火、回火及黄焰等现象。
