[资源] 最近APL上两篇关于模量关联的文章

最近接连发表的两篇关于模量关联的文章。
The correlation between shear elastic modulus and glass transition
temperature of bulk metallic glasses

Based on Varshni equation, the shear elastic modulus at the glass transition temperature GTg and
the shear elastic modulus at 0 K G0 were calculated from the elastic modulus measured at room
temperature for various bulk metallic glasses BMGs. The GTg /G0 ratios for various BMGs are
almost the same and have a value around 0.85. This unique correlation implies that the glass
transition occurs when the shear modulus of a BMG decreases to about 85% of G0. This
correlation between shear modulus and glass transition is of significance in understanding the glass
transition of BMGs. © 2009 American Institute of Physics. DOI: 10.1063/1.3093879

Correlation between average melting temperature and glass transition
temperature in metallic glasses
Zhibin Lu and Jiangong Lia
MOE Key Laboratory for Magnetism and Magnetic Materials, Institute of Materials Science and
Engineering, Lanzhou University, Lanzhou 730000, China
Received 17 November 2008; accepted 22 January 2009; published online 12 February 2009
The correlation between average melting temperature Tm and glass transition temperature Tg in
metallic glasses MGs is analyzed. A linear relationship, Tg=0.385Tm, is observed. This
correlation agrees with Egami’s suggestion Rep. Prog. Phys. 47, 1601 1984. The prediction of
Tg from Tm through the relationship Tg=0.385Tm has been tested using experimental data
obtained on a large number of MGs. This relationship can be used to predict and design MGs with
a desired Tg. © 2009 American Institute of Physics. DOI: 10.1063/1.3081028
