将冷轧态的65％Ni的铁镍坡姆合金在480℃长时间退火热处理,其冷轧态及经不同时间退火样品的室温穆斯堡尔谱的特征如下:1.各谱都由铁磁性的六指峰组成。2.各峰的线宽都很宽。3.线宽明显不对称。4.增加退火时间使谱形不对称增加,并使谱线变宽。用Hesse法计算所得的超精细场分布的特征如下:1.超精细场分布范围在250至340kOe之间。2.冷轧态样品超精细场基本上以300kOe为中心对称分布,随着退火时间的增加,其分 The cold-rolled 65% Ni Fe-Ni alloy was annealed at 480 ℃ for a long time. The characteristics of the room-temperature Mossbauer at cold-rolled and annealed at different time were as follows: 1. Magnetic six finger composition. 2. The width of each peak is wide. 3. The line width is obviously asymmetrical 4. Increase the annealing time to increase the spectral asymmetry and broaden the spectrum. The Hesse method calculates the resulting hyperfine field distribution as follows: 1. The distribution of hyperfine fields ranges from 250 to 340 kOe. 2. Cold-rolled samples of ultra-fine field basically 300kOe symmetrical distribution center, with the annealing time increases, the points
