A group of researchers published a paper on the development of a new aluminum alloy that is 100 times more resistant to space radiation damage compared to materials currently used in spacecraft.
One of the researchers, from the University of Leoben in Austria, and the other authors mixed aluminum with a magnesium alloy with zinc and copper at high pressures and came up with a new alloy capable of maintaining its shape and stiffness in this condition.
Also, in an attempt to keep the material from becoming brittle, they heated it to over 200 degrees, so that the grains that form it were the size of nanometers. The procedure helped to maintain the flexibility and strength of the material.
Later, in another phase of the research process, they carried out new tests consisting of firing different doses of energy ions, discovering that this alloy was one hundred times more resistant to radiation doses than aluminum 6061, which is widely used in this sector.
Studies suggest that the material could be suitable for future spacecraft and human exploration in the solar system, a venture that will require solutions that can withstand hostile environments, although other uses are not ruled out.
