Secondary ageing, that is microstructural evolution occurring at room temperature after short heating at temperatures above the metastable phase boundary of Guinier-Preston zones, has been studied for an Al-Cu-Mg alloy with a high Cu-to-Mg ratio. Com

Vacancy-solute aggregates formed in the alloy Al-Cu (4.38 wt %)-Mg (1.62 wt %) were studied by two different positron annihilation techniques (lifetime spectroscopy and two-detectors Doppler broadening spectroscopy) and by differential scanning calor

Electrical resistance measurements, performed during continuous temperature rise, have been carried out on a series of commercial tempers of the AA 7012 Al-Zn-Mg alloy. Results confirmed previously obtained DSC data about the presence of a Guinier-Pr

A scanning electrical resistivity (SER) study is performed during linear temperature decrease from the αSS zone in an AI-22 at% Zn alloy. The kinetic aspects of αSS decomposition during the depletion of the AI-matrix from solute Zn atoms are consid

Mossbauer spectroscopy and Doppler-broadening measures (alloy Fe44 Ni36 P14 B6) indicate that on increasing the cooling rate, the spin and charge density increases as well as the free-volume content. It is proposed that the local density fluctuations

The thermal stability of CVD amorphous WSi 2,4 thin films from room temperature to 800°C has been studied by “in-situ” sheet resistance measurements. X-ray diffraction patterns show that two consecutive phase transformations were observed. The f

A series of amorphous alloys of Fe80B20, with a constant amount of transition metal substitution and the nominal composition Fe75TM5B20, have been obtained by the “melt-spinning” technique. Differential scanning calorimetry, resistivity, small an
