(Summary description)Researchers at Purdue University in the United States have developed a super strong aluminum alloy material with great potential for industrial applications. Most lightweight aluminum alloys are soft and have low mechanical strength, which predisposes them to a wide range of industrial applications. This high-strength lightweight aluminum alloy is comparable in strength to stainless steel.

Information
Researchers at Purdue University in the United States have developed a super strong aluminum alloy material with great potential for industrial applications. Most lightweight aluminum alloys are soft and have low mechanical strength, which predisposes them to a wide range of industrial applications. This high-strength lightweight aluminum alloy is comparable in strength to stainless steel.
    
The results are published in the latest issue of Advanced Materials and Nature Communications in November 2017. This paper focuses on how to change the microstructure of aluminum material to obtain high strength and ductility. This high strength aluminum alloy is produced by introducing "stacking stacking faults" or distortions in the crystal structure. A metal lattice is made up of a series of repeating atomic layers. If one is missing, it is called a stacking fault. The twin boundary is composed of two stacking faults.
 
A stacking fault, known as the 9R phase, is of very special significance. The researchers used a special method to introduce both the 9R phase and the twin boundary into the aluminum to improve strength, ductility and thermal stability. The industrial application of this material will revolutionize the automotive and aerospace industries.
