Which consequence results when a 10th-century astrolabe craftsman anneals a brass alidade experiencing excessive heat?

💡 Explanation

Annealing the brass alidade increases its Microstructure recrystallization, softening the metal rather than hardening it, resulting in increased ductility, because this process rearranges grain structure and reduces stress. Therefore, brass becomes less brittle, suitable for delicate adjustments, rather than improvements to strength or corrosion.
