The magnetostriction of rapidly quenched Tb (Fe1-xMx)2 alloys with M=Co, Ni, Mn, Cr, Ti, V was investigated at room temperature. The values of λs at low content of x (x=0.05 for M=Ti, V, Mn, Ni, x=0.1 for M=Cr, x=0.2 for Co) were 1500∼1700×10-6 and did not show an appreciable dependence on M elements. Above x ≥0.1λs values decrases rapidly with anincreasein the M content for M=Ti, V, Cr. The magnetic sofness was evaluated from the magnetostriction at remanence (λR) and the magnetic softness parameter H′c. The Tb(Fe0.9Mn0.1)2 a1loy shows the best magnetostriction property, where the values ofλs, λ R and H′c were 1400×10-6, 620×10-6, 24 kA/m, respectively.
