Aluminium alloys are developed as airplane body due to their lighter weight compared to steel and good formability. Aluminium 7XXX series with Zn and Mg alloying elements is commonly used because its mechanical properties can be improved through a de

Ultrasonic testing (ultrasonic testing) utilizes high-frequency sound waves to detect damage to a material, composite or workpiece. This test is commonly used to inspect materials made of metal or plastic, as long as the material is not absorbent. In

The primary material to make bullet shell, cartridge brass (with 28–32% Zn), is required to have proper ductility and controlled recrystallization. These properties will reduce cracks when bullet shells are fabricated and deformed up to 70%. In ord

Studies regarding the recrystallization texture of brass alloys are quite complex. Previous experiments showed that the addition of the alloying elements on brass alloys affect the deformation mechanism and texture development. Alloying elements prom

Bullet cases are usually made of Cu-28Zn alloy through various kinds of process such as cold rolling, deep drawing, and annealing. Alloying is needed to improve properties that increase forming capabilities of cartridge brass, one option is by additi

Al-brass alloys (Cu29.5Zn2.5Al wt. %) were produced by gravity casting and homogenized at 800?C for 2 h, resulting in a binary phase morphology identified as cubic ? and martensitic ?? phases through X-ray diffraction (XRD). Samples were then subsequ
