Summary
"By precise X-ray measurements, the lattice parameter of pure nickel (Fisher Co., reagent grade) was found to be 3.52389 Å at 25°C. At the same temperature, the lattice parameters of iron samples were found to be: 2.86621 Å, 2.86624 Å and 2.86614 Å for purities of 99.999%, 99.985% and 99.9%, respectively. By measuring high angle back reflection lines, the linear coefficients of thermal expansion of both nickel and iron were precisely determined. Both, high purity nickel and iron, exhibited anomalies in their expansion coefficients near their Curie points. This is in agreement with some of the previously reported data. Some data in literature show no change in lattice expansivity of iron at the Curie point. In an effort to explain the disagreement, the effect of nitrogen dissolution on the lattice parameter of iron was investigated. It was found that nitrogen decreases the Curie temperature of iron and that this shift is related to its concentration in iron. At a concentration of 110 p.p.m., the expansion coefficient of iron remained almost constant between the temperatures: 730° and 780°C. There was no effect of nitrogen on the lattice parameter of iron at room temperature and temperatures well above the Curie point of 780°C (within error limits)"--Abstract, page ii
