Lead-rich intermediate phases, in particular Pt,,Pb and PbO, are found to form on Pt(ll1) atop Ti-buffered Si substrates prior to formation of Pb(Zr, -*TiX)O3 (PZT) thin films. Pt,_,Pb is a [ill] textured transient intermetallic phase that nucleates PZT[111] texture. PbO is a [OOl] textured layer compound that nucleates PZT[100] texture. The formation conditions and lattice matching of these in...

Sn–9Zn solder joints containing Ag nano particles were prepared by mechanically mixing Ag nano particles (0.3, 0.5 and 1 wt%) with Sn–9Zn solder paste. In the monolithic Sn–Zn solder joints, scallop-shaped AuZn3 intermetallic compound layers were found at their interfaces. However, after the addition of Ag nano particles, an additional uniform AgZn3 intermetallic compound layer well adhered to ...

Abstract High as-cast strength die-cast AlSi9Cu2Mg alloy was achieved with industrially acceptable ductility, via the addition of titanium diboride nanoparticles. The main intermetallic compounds in were identified as θ–Al2Cu and Q–Al5Cu2Mg8Si6 phases. Fe-rich compound formed present a high Mn/Fe ratio 3:1 determined BCC structured α–Al15(Fe,Mn)3Si2 phase lattice parameter a = 1.2702 nm, had hi...

An Al-40.0Ge-3.4Si wt.% alloy foil with a thickness of 50 ± 5 μm, obtained via an ultrafast solidification method, is described in this work. A complete wetting the aluminum substrate angle 0° observed, and formation drop 30 5° observed on steel substrate. Similar dissimilar brazed joints AA 6082 stainless-steel AISI 304 are obtained. The microstructure 6082/AA seam homogeneous contains particl...
