2015年5月11日 · Cartridge brass, Cu – 30% Zn, has been used for many years to produce cartridge cases for ammunition due to its superior cold forming characteristics. This article …

Figure C shows the twinned austenitic grain structure of cartridge brass that was etched producing grains with different contrast in black and white. Note that unlike the flat etched …

2025年1月16日 · Brass plays a crucial role in metalworking and manufacturing, particularly in the production of small non-ferromagnetic and non-sparking components like hinges and signage …

Each grain is a distinct crystal with its own orientation. The areas between the grains are known as grain boundaries. Within each grain, the individual atoms form a crystalline lattice. Each …

2020年3月2日 · Brass is a binary alloy composed of copper and zinc that has been produced for millennia and is valued for its workability, hardness, corrosion resistance, and attractive …

samples with pre-annealed at 500oC structure have been performed successfully. However, according to analysis of crystal grain size change, brass triple treatment with ECAP does not …

Grain structure of the neck and shoulder of the cases remains constant for at least the same ten reloading cycles. The accuracy of induction annealing is not affected by case cleanliness. The …

In this study, we designed a novel heterogeneously optimized TMC for the first time, which features fine grain/coarse grain (FG/CG) regions embedding in-situ interfacial...
