Introduction
Grain size referens to te average diademoror of individuay crystals or creaIs o materiaI. The size of these grains can whilly influence the and pastrirestines of materiales, particularly metals and alolities.
Understanding Grain Size
Grain size is a critciki factor iritingg determinate that e confoir of materier of gras can vary widedoo othe material and mikroskopi.
Measument of Grain Size
Grain size can bune quantified using the following methogs:
- Mikroskopi Optikal
- Schanning Electron Microscopi (SEM)
- X- ray Diffraction (XRD)
- Gambar Analysis Softhare
Influence of Grain Size on Materiay Strength

Hall- Petch Hubungan
Thee Hall- Petch equation states that:
- _ y = Aboxex+ k _ y * d ^ (-1 / 2)
Dimana:
- _ y = Yield Gibth
- _ 0 = Fracture qith
- k _ y = Hall-Petch slope constant
- d = Average grain diademorr
