摘要/Abstract

摘要： 在过去关于亚稳相工作的基础上，进一步分析了亚稳相的特征：第1，提出了熔体的三个温区；第2，在模糊区中存在“多态”的概念；第3，对某些合金熔体可能不存在单相区；第4，EinsteinDebye粘度的扩散理论η∝kT/(df.D)的公式在过冷区中已不再正确.

关键词: 熔体, 粘度, 亚稳相

Abstract: On the basis of the work about metastable phase in alloy melts, the characteristics for it are analyzed further as follows. Firstly, the three temperature zones in the melts are brought forward. Secondly, the concept of “multistate" exists in the ambiguous zone. Thirdly, the absence of single phase zone is possible for some alloy melts. Fourthly, the viscosity theory on the fluid cluster diffusion proposed by EinsteinDebye (η∝kT/(df.D)) is no longer applicable in the supercooled region.

Key words: viscosity, metastable phase , alloy melts
