The self-diffusion of nickel and the diffusion of Ni63 into iron, cobalt, and two iron–nickel alloys was studied using the technique of decrease in surface activity, The nickel self-diffusion results are compared to previously reported values. Nickel is found to diffuse more slowly than iron in the iron-rich portion of the iron–nickel system. The rate of nickel diffusion increases with increasing nickel content. A comparison is made between the present results for diffusion of Ni63 into iron, cobalt, and nickel with reported values for diffusion of Co60 and Fe59 in the same metals. In each solvent, the magnitudes of the activation energies, Q, are such that QNi > QCo > QFe.

Results of laboratory determinations of thermal conductivities in the temperature range −150 to 540 deg C are presented for 12 iron-nickel alloys. Six samples are of low nickel content, in the range from 1 to 9 per cent, and six others have nickel contents in the range from 35 to 80 per cent. A sample of AISI 1015 steel is included for comparative purposes. The determinations were made on bar specimens about 2.54 cm in diameter and 37 cm long, by an absolute steady-state method with heat flowing longitudinally in the bar. Computation of results from observed data was effected by means of a digital computer.

Magnetizations of single phase binary iron + nickel alloys have been measured and Bohr magneton numbers p estimated for body-centred cubic alloys with 0 to 32.3 at. % of nickel and for face-centred cubic alloys with 31 to 80 %. Initially p increases at the rate 1.1 ±0.1 μ B per nickel atom in iron-rich b.c.c. alloys. In the f.c.c. phase p increases as the nickel content decreases, and then falls very sharply as the nickel content further decreases below 40 %. In the small range of composition where either phase can be obtained, the magnetization differs widely between the two crystal structures.
