Temperature dependence of the TEMF of the thermocouple: Cu-pressed Ni_85.8Fe_10.6W_1.4Cu_2.3 alloy powder: (a) first heating of the nonannealed sample to 150°C; (b) second heating of the preannealed sample to 150°C for 45 minutes at 150°C; (c) third heating of the preannealed sample to 360°C for 45 minutes at 360°C; (d) fourth heating of the preannealed sample to 420°C for 45 minutes at 420°C; (e) fifth heating of the preannealed sample to 460°C for 45 minutes at 460°C; (f) sixth heating of the preannealed sample to 520°C for 45 minutes at 520°C; (g) seventh heating of the preannealed sample to 560°C for 45 minutes at 560°C; and (h) eighth heating of the preannealed sample to 600°C for 45 minutes at 600°C.
