This work is motivated by an industrial interest in gaining a better understanding of the phase transformations that govern the mechanical properties of 18-carat gold alloys commonly used in jewelry applications and luxury watchmaking. These alloys fall in ...
The mechanical loss and dynamic modulus temperature spectra of two 18-carat white gold alloys, Au58%Cu24%Pd18% without (grade A) and with alloying additions (grade B), were measured in the 400-1000 K temperature range. A peak interpreted as a Zener relaxat ...
Spatial encoding in MRI is conventionally achieved by the application of switchable linear encoding fields. The general concept of the recently introduced PatLoc (Parallel Imaging Technique using Localized Gradients) encoding is to use nonlinear fields to ...
Atomic ordering and stress-induced ordering (Zener relaxation) were studied in a series of 18-carat (75 wt%) yellow gold alloys (Au-Cu-Ag) by means of isothermal mechanical spectroscopy with a forced torsion pendulum at low frequencies. In the high-tempera ...
Isothermal mechanical spectroscopy by means of a forced torsion pendulum (measuring internal friction/mechanical loss) was used to study the interplay of long-range atomic order and stress-induced diffusion (Zener relaxation) in Au57%Cu43%. Our results sho ...
