Window glass becomes this way because its molecules lack the organized, repeating pattern found in crystals.
Difficulty: EasyRapid cooling of austenitic steel below 200°C triggers this phase change that creates an extremely hard, needle-like microstructure.
Difficulty: MediumThis mechanism in dislocation theory describes how a segment bows out between pinning points to generate new dislocation loops under applied stress.
Difficulty: HardAdding this element to iron creates the corrosion-resistant alloy found in kitchen sinks and surgical tools.
Difficulty: EasyThis mechanism increases alloy strength when dissolved atoms of different sizes distort the crystal lattice, impeding dislocation movement.
Difficulty: MediumThis electron microscopy condition occurs when the diffraction vector is perpendicular to the dislocation line, making the dislocation invisible.
Difficulty: HardThis yellow precious metal is so malleable that a single ounce can be beaten into a sheet covering 100 square feet.
Difficulty: EasyThis hexagonal form of boron nitride has a layered structure with sliding sheets, serving as a high-temperature industrial lubricant.
Difficulty: Medium
