Do Boron and Silicon form metallic-type bonds in alloys?

For context I am a physics student currently doing a project that involves metallic glasses. I am trying to figure out if you can get Ionic bonds inside an alloy with metalloids. More specifically, I have 2 examples.


* Iron,Nickel,Boron
* Palladium, Copper, Silicon


I have recently found out about Arkel–Ketelaar triangles and assume they answer my question but I'm not entirely sure how to use them in the context of an alloy of three components. I am also not sure if I need to use a particular measure of electronegativity or if any will do.
