Study of the Ultrasonic Behavior in (α + β`) Brass Alloy
Copper is one of the few metals with significant commercial uses. Although frequently used as a pure metal or with small amounts of metal additives, copper can form 82 binary alloys. Two of the most common are brass (copper-zinc) and bronze (copper-tin). This research work tries to study the ultrasonic behaviour in one of the important brass alloys represented by (α + β`) brass alloy. Specimens of (α + β`) brass were machined to cylindrical shape with different thicknesses in order to study the effect of the sound scanning distance on the acoustic attenuation of the ultrasonic waves. The results indicate that it is plausible to inspect (α + β`) brass using both 2MHz and 4MHz frequencies, and that the acoustic attenuation of ultrasonic waves has increased when 4MHz probe was used. In addition, the results illustrate that the acoustic attenuation increases as the sound path distance increases.
