There are numerous manufacturing processes used for metal powders production. Metal powders have been widely utilized in various industry applications, such as additive manufacturing, powders metallurgy, metal injection molding and shot penning etc. Although additive manufacturing has been recognized as having the highest value in metallurgical industry and thus become the key development projects...
MAM (Metal additive manufacturing) is a technology that produces three-dimensional parts layer by layer from metal powders. Most of metal powders for MAM are produced by gas atomization processes due to its flowability and purity. Related studies have shown the benefits of using gas-atomized metal powder in recent years. Although gas atomization process are commercially used in metal powder production...
Hot compression tests of Mg-3Al-1Zn magnesium alloy were performed at temperatures between 300-500 °C and strain rates between 0.03 and 90 s−1. Dynamic recrystallization of the alloy is developed by the necklace mechanism. At the temperature of 300 °C, structures are fully dynamic recrystallized except at intermediate strain rates. As temperature rises to 400 °C, structures are fully recrystallized...
