Abstract
In an example of a method for forming a high-strength, lightweight alloy, starting materials are provided. The starting materials include aluminum, iron, and silicon. The starting materials are ball milled to generate the high-strength, lightweight alloy of a stable AlxFeySiz phase, wherein x ranges from about 3 to about 5, y ranges from about 1.5 to about 2.2, and z is about 1.
Claims20
A method for forming a high-strength, lightweight alloy, comprising:
- ball milling starting materials including aluminum, iron, and silicon, to generate the high-strength, lightweight alloy of a stable AlxFeySiz phase, wherein x ranges from about 3 to about 5, y ranges from about 1.5 to about 2.2, and z is about 1.
A method for facilitating uniform mixing and alloying during formation of a high-strength, lightweight alloy, the method comprising:
- adding starting materials and a grinding medium to a ball mill, the starting materials including aluminum, iron, and silicon;
- adding an anhydrous liquid medium to the ball mill with the starting materials and the grinding medium;
- and
- ball milling the starting materials in the presence of the grinding medium and the anhydrous liquid medium to generate the high-strength, lightweight alloy of a stable AlxFeySiz phase, wherein x ranges from about 3 to about 5, y ranges from about 1.5 to about 2.2, and z is about 1.
