Magnetostriction measurements on single crystal and polycrystal TbFe$sub 2$ and ErFe$sub 2$ are reported and compared. For TbFe$sub 2$, the largest known room temperature magnetostriction constant is found: lambda/sub 111/ = 2400 x 10$sup -6$. For ErFe$sub 2$: lambda/ sub 111/ = -300 x 10$sup -6$ lambda/sub 111/ is the dominant magnetostriction constant and the major source of the magnetostriction of the polycrystalline rare earth--Fe$sub 2$ alloys. TbFe$sub 2$ possesses the largest known cubic anisotropy constant. At room temperature K$sub 1$ = -7.6 x 10$sup 7$ erg/cm$sup 3$. The sign of the anisotropy plays an important role in determining the field dependence of the polycrystalline magnetostriction. (auth)
