冷却速度与Ce含量对快速凝固Al-Ce二元合金组织的影响

EFFECT OF COOLING RATE AND Ce CONTENT ON STRUCTURE OF RAPIDLY SOLIDIFIED Al-Ce BINARY ALLOYS

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 was found to facilitate the formation of granular disperse phase. While the alloys with definite composition may easily precipitate globular grains of higher dispersity if the cooling rate was accelerated.
