Influence of property of self-fusible alloy powders on coating microstructure;

Investigation on argon arc cladding technology of Ni-based self-fluxing alloy;

Chemical composition, physical properties, microstructure and hardness of the manufactured Fe-Ni-RE self-fluxing alloy coating have been investigated and compared with Ni60 alloy, Although the Fe-Ni-RE self-fluxing alloy powder contained higher Fe and lower Ni and Co contents, than Ni 60 alloy whose main properties were at the same level.

Design and properties of Bi-Sn-In ternary fusible alloys;

Temperature-dependent fuse is one of the important parts in (smoke) fire dampers, and the fusible alloy is the key element of the fuse.

Fusible alloys are the alloys with the melting point below 232°C (meltingpoint of Tin), and normally composed by bismuth, lead, tin, and indium elementsin different proportions depending on the desired properties.

The calculation results showed that although the activity of Si-Ca alloy confirms fairly with measured data, the activity curves of Si-Ca and Si-Ba alloy melts show relatively great negative deviation from the idea melt.

According to the Miedema formation heat model and retated thermodynamic data, the activity of Si-Ca binary alloy melt at 1 623 K was calculated.

The electromagnetic separation of Si phase from (Al-Si) alloy melt been in vertical, incline and horizontal states were investigated experimentally in high frequency electromagnetic field.

The Chinese development tendency of new foundry technology was epitomized in seven parts——cast alloy, molding materials, alloy smelting, sand casting, special casting, casting quality ensurement and developing foundry communication.
