A novel Al matrix composite reinforced by nano-AlNp network
In pursuit of lightweighting of automobiles and low emission of transportation, the efforts to develop high-strength, heat-resistant and fatigue-resistant Al alloys and/or composites have been ongoing. Here we report a novel Al matrix composite with ultrahigh strength reinforced by a three dimensional network of nano-AlN particles for the first time. The in-situ synthesized AlN particles are co...
متن کاملStable Quasicrystalline Phase in Al-Cu-Fe-Cr Coating Materials
Transmission electron microscopy (TEM) studies have been carried out on magnetron-sputtered coatings in the Al-rich region of the Al-Cu-Fe-Cr quasicrystalline phase field, focusing on the composition that exhibited the best tribological performance among a group of sputtered coatings. The size of the particles in the as-deposited coating is around 10 nm. The TEM experiments on annealed coatings...
متن کاملLaser processing and microstructure of Al-Cu-Fe quasicrystalline coatings on Al-base materials
There is a large interest in using high power lasers for surface alloying or cladding on aluminium alloys, in order to enhance hardness and to improve wear resistance. A partly quasicrystalline surface layer (QC) (Al-Cu-Fe coating) has been obtained by laser cladding on Al-base materials. In addition to crystalline phases (Al5Fe2 and AlisFe4t -with dissolved copper), a quasicrystalline Al-Cu-Fe...
متن کاملRoom Temperature Oxidation of Al-Cu-Fe and Al-Cu-Fe-Cr Quasicrystals
We have investigated formation of oxides on quasicrystalline and crystalline alloy surfaces of similar composition, in different oxidizing environments. This includes a comparison between a quaternary orthorhombic approximate of Al-Cu-Fe-Cr quasicrystal and the ternary AI-Cu-Fe quasicrystalline and crystalline phases. We noted that each sample showed the following common trends: preferential ox...
متن کاملProcessing Of Al-Cu-Fe Single Grains
The phase equilibria of the Al-Cu-Fe quasicrystalline phase (y phase) is complex and conventional crystal growth techniques like the Bridgman and Czochralski methods are not applicable in preparation of large crystals. Large single grains of the y phase been have prepared by either slow cooling or isothermal anneals. In the later technique, arc melted ingots were subjected to either single or m...
