Metallurgical failure analysis is like a detective game. You are looking for clues to figure out what happened to the metal or metal part that broke. Scientists use tools like microscopes and special tests to look at the metal and the pieces that broke off, and they look for clues like cracks, rust, different colors, shapes, and sizes. Once they have gathered all the clues they need, they can figure out what caused the metal or metal part to break and why. By understanding what happened and why, scientists can help people fix the problem and make sure it doesn't happen again.
