Structure and Microhardness of Cu-Ta Joints Produced by Explosive Welding

Structure and Microhardness of Cu-Ta Joints Produced by Explosive Welding

The structure and microhardness of Cu-Ta joints produced by explosive welding were studied. It was found that, during explosive welding, an intermediate layer 20⋯40  μ m thick with a finely dispersed heterophase structure, formed between the welded copper and tantalum plates. The structure of the layer was studied by scanning and transmission electron microscopy. Microvolumes with tantalum part...

Thermobimetals Mechanical Properties Produced by Explosive Welding with Rolling

We used explosive welding with rolling to produce tliermobimetals on the basis of beryllium bronze and alloys of nickel. It gave us possibility to obtain magnetic and 11011magnetic tliermobilnetals possessi~lg high pllysical and mechanical propel-ties.

Structure Improvement of Aluminothermic Welding Joints by Using Modifiers

Aluminothermic rail welding was from the beginning a great success because its low price even in 1895 in Germany. This method is now, widely used all over the world for the railways construction, maintenance and modernization. Instructions give you guidelines for preparing papers for conferences or journals. After 1989, the welding needs of the potentials beneficiaries (Romanian Railways, Urban...

Strength of joints produced by transient liquid phase bonding in the Cu–Sn system

The paper focuses on the strength and toughness of joints produced by transient liquid phase (TLP) bonding in the Cu–Sn system. It is motivated by potential applications of TLP bonding in attachment of high-temperature wide bandgap devices to ceramic substrates. Model test specimens suitable for mechanical testing are developed, utilizing substrates of oxide dispersion strengthened copper. Thre...
