结果表明，在铸造过程中，静压室压力P的增加抑制了Zr 65 Al 7.5 Ni 10 Cu 17.5合金的非晶形成能力，相反却提高了Zr 65 Al 7.5 Ni 10 Pd 17.5合金的非晶形成能力。在这些合金中，GFA对P的这种相反的依赖性可能是因为初级结晶使体积增加或减少。
It is found that an increase in the hydrostatic chamber pressure (P) during the casting process suppresses the glass forming ability (GFA) of the Zr65Al7.5Ni10Cu17.5alloy, on the contrary, it enhances the GFA of the Zr65Al7.5Ni10Pd17.5alloy. This opposite dependence of the GFA on P in these alloys may be because the volume increases or decreases by the primary crystallization.
