Title: | Deformation behavior and indentation size effect in amorphous and crystallized Pd₄₀Cu₃₀Ni₁₀P₂₀ alloy | Authors: | Li, N Liu, L Chan, KC |
Issue Date: | May-2009 | Source: | Journal of materials research, May 2009, v. 24, no. 5, p. 1693-1699 | Abstract: | The deformation behavior and indentation size effect (ISE) in amorphous and crystallized Pd₄₀Cu₃₀Ni₁₀P₂₀ alloy were comparatively studied through instrumented nanoindentation. It was found that the two alloys showed different deformation behaviors, the amorphous alloy exhibited conspicuous pop-in events in the load-depth (P-h) curve, while the crystallized alloy showed a relatively smooth P-h curve. In addition, the indentation hardness was observed to decrease with increasing penetration depth in the two alloys, exhibiting a significant ISE. However, the crystallized alloy displayed a sharper reduction of hardness with indentation depth as compared to the amorphous alloy, indicating a more significant indentation size effect in the crystalline alloy. The structure difference and friction factor associated with the surface residual stress are taken into account to interpret the difference in the deformation behavior and indentation size effect of the two alloys. | Keywords: | Amorphous Crystalline Hardness |
