Americans and Canadians have created the toughest and strongest material known to date. It is a metallic glass consisting of palladium (90%), silver, germanium, silicon and phosphorus.
This new 'supermaterial' is extremely strong and as tough as steel, according to a report this week the journal Nature Materials. " Strength refers to their ability to bear weight and resistance, which can absorb shock without breaking. This is the first time scientists have found a material capable of combining these two features with such a high degree of satisfaction. The research team leader is responsible for finding Marios Demetriou, Institute of Technology California (USA).
normal metals are weak and malleable because they have a crystalline structure and carry much weight when their atoms slide over each other. On the contrary, it is very difficult to change the form of amorphous metals, with a structure that resembles glass, but once they begin to crack break away. However, the new 'supermaterial' deforms before breaking.
The biggest drawback of the new material is its price. Its lead compound, palladium, worth more than 19,000 € / kg so far only have medical applications such as bone fracture healing.
During the study, scientists also investigated the properties of other metals such as aluminum or iron and may in the future to develop new materials cheaper than those used today, based on steel.
