Pure titanium metal in photo
Fans of Ayn Rand's 'Atlas Shrugged' will recognize this one
In a article published by Sang-Heon Kim, Hansoo Kim & Nack J. Kim of the Graduate Institute of Ferrous Technology, POSTECH, Pohang 790-784, South Korea.
They discovered a new alloy that combines Aluminum, Steel and a small amount of Nickel to make a metal as strong as Titanium.
Previous attempts at making this alloy resulted in brittleness because of the crystalline structure.
Simply put it made hard yet brittle metal.
The Nickel on the other hand disperses the crystals so that they do not form as large, and in a structure that is both strong and light.
However full scale production is still a small ways off as the current mill process uses silicates to prevent steel from oxidizing during production. The silicates react with the process so another method will need to be devised. Otherwise the whole process could be performed in existing mills without modification to equipment.
My hopes is that the laser sinter for 3D printing using ordinary $5 a pound Titanium dioxide powder becomes a reality as this alloy still will not have the heat resistant qualities of actual titanium.
