There’s been plenty of work, but It’s a hard one to elucidate physical mechanisms for because they are super rare in terms of the number of potential initiation sites... You have to get lucky if you want to observe the material state before the whisker formed
It’s become more of a practical problem since the restrictions on leaded solders, since lead-free solder alloys seem more prone to whisker formation...
