Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by physicists shows that the gold standard for ...

“It is about 3-4 times harder than most steels,” said Emilia Morosan, the lead scientist on a new study in Science Advances that describes the properties of a 3-to-1 mixture of titanium and gold with ...

A chance discovery in a physics lab at Rice University has turned up an ultra-hard material that could usurp the titanium commonly used in today's knee and hip replacements. Scientists have found that ...
