Abstract
We used electron-energy-loss spectrometry to measure the intensities of the Cu white lines found at the onsets of the L2 and L3 absorption edges of rapidly quenched CuZr, CuTi, CuPd, CuPt, and CuAu. Enhancements of the white lines in the alloys as compared to elemental Cu were correlated with changes in the 3d occupancy of Cu atoms upon alloying. We found that the Cu atoms lost 0.2±0.06 d electrons when alloyed with Ti or Zr, 0.0-0.0+0.06 d electrons when alloyed with Au or Pd, and 0.03-0.03+0.06d electrons when alloyed with Pt. We found no strong correlation between measured 3d-occupancy changes and heats of formation of the alloys, consistent with expectations that outer s electrons play an important role in the alloying of Cu with Pt, Pd, and Au.
