-orienting effect. Accordingly, we can understand why an aligned precipitates structure was found in stress aged Al-Cu alloy in previous studies [6-9], but two variants with increased number density... the precipitate distribution and generate preferential orientation of precipitates in several age-hardenable alloy systems. This preferential orientation of precipitates structure or aligned......
