This paper presents the results of development efforts relating to an advanced material processing technique, namely cryogenic milling, and its application to the processing of Al-7.5wt%Mg-0.2wt%N-20vol%SiC and Al 8wt%Ti-2wt%Ni nano-composite materials suitable for use in aerospace fastener applications. The effects of cryogenic milling in the material production are investigated via microstructural analysis. The advantages of cryogenic milling in the material production are presented with powder morphology and handling characteristics, and microstructural and nanostructural aspects. The resulting, very homogeneous material is discussed along with resulting mechanical properties, which are obtained through tension tests.
