The US scientists have created a very strong unbreakable metallic glass by combining up to five elements, including the rare metal palladium.The glass itself is even tougher than the steel.Pladium is the main element which increases the plasticity of the glass and prevents cracks from spreading where as the other metals are just there to add strength.
Dr Robert Ritchie who is a material scientist at the U.S. Department of Energy is of the view:
'The result is that glass undergoes extensive plasticity in response to stress, allowing it to bend rather than crack.'However we have one only drawback i-e palladium is really expensive costing over £500 an ounce while as compared to this gold costs £830.But even then the doctor feels that it would flourish in the market due to its unique feature.
'Traditionally strength and toughness have been mutually exclusive properties in materials,' he added.
'We’re bucking the trend here and pushing the envelope of the damage tolerance that’s accessible to a structural metal.'
Other than pallladium, elements like phosphorous, silicon,silver and germanium that makes the thickness of the glass rods to 6mm.The glass was created by scientists at the U.S. Department of Energy and the California Institute of Technology.
