Abstract

In this study Synthesis of AL3ZR INTERMETALLIC COMPOUND from The mixed powders of aluminum and zirconium and the effect of its addition to the MECHANICAL PROPERTIES of nanocompositcs aluminum was investigated. Staichiometric ratio of Al and Zr mixed and heated to 700 C under the argon atmosphere to produce Al-Zr. The densed structure that was produced grinded to produce powder. To investigate the phase and morphology of the powders, phase analysis by XRD and scanning electron microscope equipped with an EDS spectrometer was used. Results showed intermetallic Al3Zr successfully formed and no other phase was detected. Then, the powder obtained (10, 15, and 25% by weight) mixed with different percentages aluminum powder in a planetary mill. The milling was carried out under an argon atmosphere with ball to powder weight ratio of 20:1 and speed 300 rpm. The XRD results and using the Williamson-Hall method showed that after 20 hours milling the particles are diminished dramatically in size and AL3ZR INTERMETALLIC COMPOUND 56 nanometer with nanocrystal structure is formed within the aluminum matrix. Then the mixture was formed by hot pressing. To compare the MECHANICAL PROPERTIES and compressive strength tests were carried out. The results of compressive strength test and hardness test showed that yield strength and the hardness' may be increases and elongation can be decreases by addition of the AL3ZR INTERMETALLIC COMPOUND to AI. The results showed that the composite sample with 25 wt% Al intermetallic respectively, compressive strength and hardness is equal to 498MPa and 193VHN.
