According to the phase diagram of Ag-Cu-Si system and influence of Si on Ag-Cu alloy properties,the solidus-liquidus temperature of Ag 20%～45%,Si 1%～7% and Cu-Ag-Si system filler metals were determined by DTA and their synthetic properties were studied.
This peper has summarized the methods of manufacturing superfine cemented Carbide,inhibiting mechanism of controlling grain growth and the influence of inhibitor on alloy properties have also discussed.
he chemical compositions of Ni- base cast alloy forHCl+FeCl_3 medium were designed,the metallographiccompositions and fracture faces of the alloy were observedby using metallographic microscopes and SEM,thc influ-ence of various heat treatntents on thp alloy property werestudied.
Alloying elements addition is an important method to improve alloy property or design new al- loys,and has been widely used to study and develop Mg-Al based elevated temperature magnesium alloys at pre- sent.
Nanocrystal and surface alloy properties of bimetallic
We report on the correlation between the nanocrystal and surface alloy properties with the bimetallic composition of gold-platinum(AuPt) nanoparticles.
The nanocrystal and surface alloy properties are directly correlated with the bimetallic composition.
The comparison indicates that interactions fitted to elemental metals are not sufficient to determine alloy properties.
In this situation, the unit cell volumes increase with increasing x and the enthalpy changes of hydride formation decrease with increasing x, thereby changing the alloy properties in the gas phase and the electrochemical environment.
