"Standard Specification for High-Strength Low-Alloy Structural Steel" covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction intended primarily for use as structural members where savings in weight [mass] or added durability are important. The atmospheric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition. When properly exposed to the atmosphere, this steel can be used bare (unpainted) for many applications.

This specification covers high-strength low-alloy structural steel shapes, plates, and bars for welded, riveted, or bolted construction but intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this steel in most environments is substantially better than that of carbon structural steels with or without copper addition (see Note 1). When properly exposed to the atmosphere, this steel is suitable for many applications in the bare (unpainted) condition.

This specification covers high-strength, low-alloy, hotand cold-rolled sheet and strip in cut lengths or coils, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in two types: Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check).

This specification covers low-carbon precipitation— strengthened nickel - copper - chromium - molybdenum - columbium alloy steel plates for general applications. The alloys in this specification are strengthened by precipitation in various temperature ranges. Precipitation strengthening can occur upon air cooling after hot rolling, during normalizing, and by another heat treatment. These grades are not intended for use in applications above 900°F [540°C].

This study is directed to understand the origin of that difference with a numerical simulation of the process. The mechanical behaviour of the materials was investigated in tension and hydraulic bulge test, out of comparison’s sake and to derive the hardening law over a strain range representative of the process. Finite element simulations are performed using the von Mises criterion coupled with isotropic hardening, to compare the predicted forming load and springback parameters with experimental values.

Copper alloys, including bronzes, are currently employed in a wide range of engineering applications because of their high ductility, high corrosion resistance, non-magnetic properties, excellent machinability, and high hardness. The results of this study indicate that copper alloys with excellent mechanical properties can be produced.

The performance tuning industry is brimming with misinformation regarding spark plug center electrode design, with perhaps the largest misconception of all being that because copper is a better conductor than iridium the so-called “copper” spark plugs offered by many manufacturers are also somehow superior. It is true that copper is superior to iridium in its heat and electrical conduction capabilities, however it is also a completely unsuitable material to be used as a high voltage electrode, and it not used as electrode material on any spark plug.

Mechanical alloying was used to synthesize in-situ copper based composite reinforced by binary niobiumtitanium-carbide from Cu, Nb, Ti and graphite powder mixture. The nominal composition was correponded to Cu-30 vol.% (Nb,Ti)C. XRD patterns showed that (Nb, Ti)C was not formed in the as-milled powder after 5 hours of milling but was precipitated with a subsequent sintering at 900oC. Milling time has showed a great influence on both mechanical and physical properties of the sintered composite pellets

The aim of this research is to investigate the influence of the sintering temperature on the properties of the in-situ carbide (Nb,Ti)C in a copper matrix synthesized via mechanical alloying and powder metallurgy from elemental powders of Cu, Nb, Ti and graphite. The mixture of starting powders with compositions corresponding to Cu-15vol.% (Nb, Ti)C was mechanical alloyed using a planetary ball mill for 20 hours.

The wettability of Sn-8Zn-3Bi lead free solder alloy on the copper substrate was evaluated via measuring the contact angle of the solder and the substrate. The measured contact angle was then compared to the contact angle of the traditional and widely used eutectic Sn-37Pb solder alloy. Experiments to study the effect of temperature, flux, and surface roughness of the substrate on the contact angle were also carried out.

In this present work, A356 aluminum alloy is heat treated with the addition of copper, rare earth and strontium were investigated. T6 treatment is preferred in this work (solution at 535°C for 4h + aging at 150°C for 15h) when compared to other heat treatment processes (i.e short heat treatment processes).

A sharp 120o Equal channel angular pressing (ECAP) was applied at room temperature to refine the grains sizes of pure copper and copper - 1% Chromium alloy for spot welding electrode tips application. Initially deformation behavior was investigated with the position using colorful plasticine as work piece followed by copper alloy. It was found the deformation at the central part of the work piece is heavily sheared than the outer part.
