Which outcome arises when bronze axes contain excessive tin?

💡 Explanation

Excessive tin leads to beta phase formation, causing increased brittleness, because the Alloy phase segregation encourages crack propagation under stress leading to brittle failure. Therefore, axe heads break easily, rather than deforming plastically before failing.
