Relationship between the shear moduli of metallic glasses and their crystalline counterparts

It has been shown for 24 metallic alloys that temperature dependences of the relative changes of the shear moduli in the glassy and crystalline states below the glass transition are nearly equal, provided that structural relaxation is absent. This behavior supports the idea that the shear elasticiti...

Description
Summary:It has been shown for 24 metallic alloys that temperature dependences of the relative changes of the shear moduli in the glassy and crystalline states below the glass transition are nearly equal, provided that structural relaxation is absent. This behavior supports the idea that the shear elasticities of glass and its crystalline counterpart are intrinsically interrelated, in agreement with the Interstitialcy theory. •The temperature dependences of the shear modulus in 24 alloys are analyzed.•Relative changes of the shear moduli in the glassy and crystalline states are equal.•The shear elasticities of glassy and crystalline states are intrinsically linked.•The results are being in agreement with the Interstitialcy theory.
