Researchers find cheap alloy that is as strong as titanium




Scientists at the Pohang University of Science and Technology in South Korea have published a study in which a new alloy that is described as strong and light as titanium, but only one-tenth cost.

The alloy, as described in a study which is published in Nature, is composed of iron and aluminum, to which nickel has been added as an additional ingredient. This creates a so-called inter-metallic B2 wherein the nickel reacts with aluminum and at the nanoscale B2-crystals are formed. These crystals would make the alloy is much less brittle and therefore extra strong, while the presence of the aluminum material is still light.

According to Korean scientists is the new alloy as strong as titanium, while the weight is comparable. However, the material should, if produced on a large scale, can be a factor of ten lower than the relatively expensive titanium.

The use of steel for example, takes the manufacturing of cars off because vehicles are increasingly built lighter in order to reduce fuel consumption. Aluminum is not always suitable for cars because it is not sufficiently strong. Possibly, this new alloy new options to the automobile industry.
