The nanostructural evolution and phase transformation of the films of a Zn-Al based alloy (Zn¬68Al¬10Cu¬22 in wt pct) have been studied by using X-ray diffraction and scanning electron microscopy. Nanostructural thin films of the Zn-Al based alloy were produced by using an electron beam deposition t...

The ageing behavior of Mg-xAl-Zn alloys with a variation of Al contents (x=3, 5, 7, 9 and 11 wt pct) were investigated. Solid solution treatment and artificial ageing were carried out at 693 and 493 K, respectively. After the solid solution treatment, β-Mg17Al12 was resolved to the α-Mg matrix in th...

Precipitation study was carried out in Ni-35 at. pct Cr alloy by measuring electrical resistivity at different ageing temperatures and long ageing times. During ageing, it was observed that electrical resistivity initially rose with ageing time and then fell after very long ageing at a constant temp...

Electron enregy loss spectroscopy (EELS) and energy filtering transmission electron microscopy (EFTEM) investigation on 2.25Cr-1Mo steel was carried out to understand the nature of evolution of secondary carbides. The filtered images obtained from two different ageing treatments indicate that the st...
