Microstructure And Properties

ABSTRACTThe microstructure and properties of thin films depends strongly upon the alloy composition. A study was made of the metallurgical aspects of homogeneous Al alloy films, particularly the binary Al-Ti and the ternary Al-Ti-Si systems. Electrical resistivity, grain size morphology, second phase formation and electromigration have been studied as a function of the alloy composition and its heat treatment.

7075 Al Alloy

The variation of microstructure and properties of RE-7075 Al alloy after homogenizing annealing were studied by some modern analytical instruments which including OM(optical microscope),SEM(scanning electron microscopy),EDS(energy dispersive spectroscopy ), Brinell hardness and conductivity meter of SIGMASCOPE SMP10 type in this experiment. The results shows that the alloy′s microstructure was uniform ,reduced the volume fraction of second phase,increased supersaturation of matrix and eliminated gradually dendritic segregation in homogenizing annealing state. The primary phase of matrix microstructure contain α(Al),T(Al2Mg3Zn3) and grain boundary microstructure include α(Al),Al2Cu,AlCuMg4La4 after homogenizing annealing.Compared with as cast condition,the conductivity and the hardness reduced after homogenizing annealing.
