US researchers have found that the alloy is four times more stable than titanium

US scientists have found a substitute for titanium in medical implants with four times the strength.

Pure titanium is an extremely tough substance and is often used in medical implant. The simple reason is that titanium is easily accepted by the body and human bone tissue can develop normally around the metal replacement part.

However, scientists at Rice University in Houston have found a compound that is four times more rigid than titanium and can also be used in medical implants .

The new alloy, called beta-Ti3Au, is made in the laboratory by mixing the molten mixture of gold and titanium. It is a mass of matter arranged between gold and titanium atoms when combined at high temperatures.

Knee-and-hip implants are usually implanted in the human body for a maximum of 10 years due to friction. The toughness of beta-Ti3Au will be an excellent option for the medical industry to extend the life of the replacement parts on the human body .

The finding has just been published in the scientific journal Science Advances.

The discovery of beta-Ti3Au is also very accidental. Professor Emilia Morosan of Rice University, Houston, said his team found the alloy while working with special magnets made of gold and titanium.

Professor Morosan revealed that beta-Ti3Au is so tough to squeeze it out in diamond mortar to check its purity. " This is the hardest alloy of gold and titan ever. With a higher hardness than many other technical alloys, the new compound allows longer tooth life and replacement joints. "

In addition, beta-Ti3Au can also be used in other industries such as drilling, sports ...
