WebCrystallites are coherent diffraction domains in X-ray diffraction. Particles are chunks/pieces (usually very small, below 1 mm) of solid matter, ensembles of atoms. Particles can be as small as two atoms (the nitrogen particle for example, [math]N_ {2} [/math]) Grains are volumes, inside crystalline materials, with a specific orientation. WebGrain-boundary strengthening (or Hall–Petch strengthening) strengthens materials by changing their average crystallite (grain) size. The size of the grain determines the properties of the metal. For example, smaller grain size increases tensile strength and tends to increase ductility. Larger grain size is preferred for improved high ...
