Abstract It has been demonstrated that high rate d.c. magnetron sputtering can easily prepare materials such as Nb3Ge and Nb3Si in a metastable state. This sputtering-system was made in an effort to stabilize the metstable phases. Specimens were quenched just after sputtering from 1100° C to liquid N2 temperature at the rate of 3500° C min−1. The relation between quenching rate and superconducting onset temperture, T c0, the transition width, ΔT c, and the lattice constant, a 0 were examined. The results show that quenching just after sputtering is very useful in preparing metastable materials.
