Fig. 5: Mechanical properties of ZTE alloys.
From: An isotropic zero thermal expansion alloy with super-high toughness
The comparison of the compressibility at fracture (εf) and ultimate strength (δUS) of various ZTE alloys5,6,8,11,12,22,27,43,44,45,46,47,48,49,50,51,52. The hollow and solid dots refer to anisotropic and isotropic thermal expansion, respectively. It is noted that Invar is a completely plastic material, for comparison, we used the compressive strength at ε = 30% strains here.
