The presence of Ni can significantly promote the CoSi-CoSi2 transformation process reducing the transformation temperature and, in consequence, the thermal budget of silicidation. In this work, silicidation of the Si/Co0.95Ni0.05/Ti system was invest

Nanostructured fluoride powders were prepared by high-energy ball milling under different milling conditions (time and intensity). To investigate the local structural orders, we combined suitable local probe techniques such as 57Fe Mossbauer spectrom

57Fe Mossbauer spectrometry was carried out on high-energy ball-milled crystalline compounds in order to study the milling effect on the Lamb–Mossbauer factor f. A comparison between metallic (α-Fe) and ionic (r-FeF3) milled powders is proposed, e

Nanostructured ZnFe2O4 ferrites with different grain sizes were prepared by high energy ball milling for various milling times. Both the average grain size and the root mean square strain were estimated from the x-ray diffraction line broadening. The
