Which outcome compromises aluminum alloy strength at grain boundaries?

💡 Explanation

Solute segregation introduces embrittlement because higher solute concentration at boundaries precipitates brittle phases. Therefore grain boundary strength decreases, rather than diffusivity increasing or vacancies being more locally resisted.
