Figure 5. Mechanical properties. (A and B) Engineer compressive stress-strain curves of 5Tb alloy (A) and 4Er alloy (B) with the inset ingots, respectively, along the LD during loading. (C) The Ashby-type plot for the typical LZTE alloys: ultimate strain, strength, and temperature window, and the mechanically machined components of 5Tb and 4Er alloys are on the right side. (D) SEM image of the fractured 5Tb ingot surface. (E) The enlarged region in (D) is signed with a red rectangle.
