Lead-free solder alloys have been around for as long as people have done soldering, with sources dating back about 5,000 years. Most of these alloys were combinations like copper-silver or silver-gold ...

Electrical conductivity: copper has the highest conductivity of the engineering metals. Silver or other elements may be added to increase strength, softening resistance or other properties without ...

With a view to constructing more durable components that can withstand the very harsh environments in and around aircraft and jet engines, NASA researchers have developed a novel metal alloy with an ...

Next-generation technology requires next-generation materials that can be tailored to exact mission requirements. Additive ...

Different methods are employed to vary cooling rates for magnesium alloys during the solidification process from liquid to solid phase and after the solution/aging heat treatment. These include using ...

In metal alloys, behavior at the atomic scale affects the material's properties. However, the number of possible alloys is astronomical. Scientists developed a theoretical model that allows him to ...

Electron backscatter diffraction (EBSD) maps of the investigated Inconel 718 alloys. Inverse pole figure (IPF) maps along the X direction (horizontal) are presented for a A wrought and fully ...

When alloys are formed by mixing with solutes, or dissolved substances, the dislocations act as preferred locations for the solutes. The solutes attach to dislocation threads like a swarm of bees, ...

Ingenious people have produced alloys since ancient times. By trial and error, they mixed metals and other elements until the whole came out better than any component alone. In recent years, some ...
