摘要:

利用TEM、XRD等分析手段研究快速凝固Al-Ti-La合金中的化合物相的结构,以及高温退火后的结构,分析化合物相的高温稳定性,并提出化合物相的孪晶形核理论.快速凝固Al-Ti-La合金形成细小、圆整、弥散的金属间化合物相,经分析为Al20Ti2(RE),金刚石立方结构,该化合物相形成孪晶,其孪晶面{111},孪晶方向[112],认为化合物相是以孪晶为晶核从熔体中优先其他化合物相形成并生长.

Abstract:

TEM, XRD and other analytical methods were used to study the structure of the compound phase in the rapidly solidified Al-Ti-La alloy and the structure after high-temperature annealing, analyze the high-temperature stability of the compound phase, and put forward the twin nucleation theory of the compound phase. Rapid solidification of Al-Ti-La alloy to form fine, round, diffuse intermetallic phase, analyzed as Al20Ti2(RE), diamond cubic structure, the compound phase to form twins, its twin surface {111}, twin direction [112], it is believed that the compound phase is formed and grown with twins as crystal nuclei from the melt preferentially other compound phases.
