B. Wolf et al., COMPARATIVE MORPHOLOGY STUDY OF INDENTATIONS IN QUASI-CRYSTALLINE ALPDMN AND SINGLE-CRYSTALLINE NIAL INVESTIGATED BY ATOMIC-FORCE MICROSCOPY, Surface and interface analysis, 25(7-8), 1997, pp. 561-568
Atomic force microscopy (AFM) was used to characterize surface modific
ations that developed from Vickers indentations into single-crystallin
e NiAl(100) and single-quasicrystalline AlPdMn (surface of fivefold sy
mmetry). Indenter rotation was used to track the competition between c
rystal and indenter anisotropy. Distinct differences between the two m
odel substances were found with respect to the lateral extension of th
e indentation-induced deformation zone, to crack formation, size, shap
e and radial extension of created structures, and volume balance betwe
en the impression and piled-up elevations. (C) 1997 by John Wiley & So
