Ini adalah sesuatu yang sangat penting yang dapat dilakukan oleh para ilmuwan. Memahami apa yang terjadi di dunia ini.

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
