We used X-ray diffraction to study the effects of cobalt and nickel on electrodeposited iron-tungsten-based alloy film amorphization. The minimum tungsten content required for amorphization decreased from <i>ca</i> 13at% in iron-tungsten binary alloys to <i>ca</i> 4at% or <i>ca</i> 7at% in ternary alloys with cobalt or nickel. A ternary alloy structure with a tungsten content less than that required for amorphization tends to be influenced by the substrate surface structure and to be stable only at low temperature. This appears to be why ternary alloys with cobalt or nickel with lower tungsten content become amorphous than iron-tungsten binary alloy.
