Abstract
This research is to investigate the influence of adding different concentrations of (0.0109, 0.0185 and 0.037wt %) La on the microstructure, electrical resistivity, Vickers micro hardness (Hv) and ultrasonic properties on 6201 aluminum alloy comparing to (6201alloy +0.021wt%TiB) used in an electrical industry. The results showed that the (6201alloy+0.037wt% La) was suitable materials for using electrical conductor than alloys added with0.0185wt%La and 0.0109wt% La. It was also found that Vickers micro hardness (Hv) measured mechanically and electrical resistivity for the alloys contaning La has the same trend to those determined from ultrasonic calculations. It was also found that the structural changes inside the matrix of the alloys play an important role in the ultrasonic wave propagation and also in controlling the electrical resistivity and the alloys strength.
