考察了冷却速度和成分对快速凝固Al—Ce二元合金组织的影响,结果表明,在相同冷却速度下,Ce含量少利于形成粒状弥散相;而成分一定时,提高冷却速度易于析出弥散度高的球形粒子。
Less Ce content in rapidly solidified Al-Ce alloys at a certain cooling rate wasfound to facilitate the formation of granular disperse phase. While the alloys with definitecomposition may easily precipitate globular grains of higher dispersity if the cooling rate wasaccelerated.
