Accordingly, five immiscibleW-based binary fcc-bcc and hcp-bcc metal systems, i.e, Cu-W, Ag-W, Au-W,Sc-W and Y-W systems, and miscible Co-Nb systems, were selected to studythe formation of metastable phase selection and glass formation ability.

• 为此,本论文选择了五个生成热为正的W基二元fcc-bcc和hcp-bcc金属系统,即:Cu-W、Ag-W、Au-W、Sc-W和Y-W系统,和一个生成热为负的Co-Nb系统来研究其亚稳相选择和非晶形成能力。
