The component elements in steel can be categorised in terms of their crystal structures. At least a basic knowledge of the practical implications of these crystal arrangements is essential to ...

DP steels contain islands of hard martensitic second phase in a ferritic matrix. Steel strength improves when the volume fraction of hard second phases increases. The formation of DP steels involves ...

Some organic crystals jump around when heated up. This happens because of an extremely fast change in their crystal structure. Scientists have now demonstrated that the crystals send out acoustic ...

For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. This is why many contain a remarkably strong and corrosion-resistant alloy ...

A new paper has been published on the unusual microstructure of smectics -- liquid crystals whose molecules are arranged in layers and form ellipses and hyperbolas -- and their similarity to ...

The micrographs below show the effect of annealing at different temperatures on a sample of Fe - 0.7 wt % C steel in which martensite has been formed by quenching. Because of the low carbon content ...

Dislocations can save lives. This stems from the fact that the one-dimensional defects in a metal play an important role when the material deforms: for example, when a car body panel crumples in an ...

• Martensitic stainless steels are strong, wear resistant, and cost less than other stainless-steel grades. • Controlling weld cooling with induction heating minimizes fusion and heat-affected zone ...

ITHACA, N.Y. - Using the latest computer game technology, a Cornell-led team of physicists has come up with a "suitably beautiful" explanation to a puzzle that has baffled researchers in the materials ...
