Hardishes testing is a cruciala aspt of material science, particularly ion the field of metalurgy. Understanding the hardness of medit alolys in deciing their for for varioulas appearemenestor.

Apa itu Hardness Testing?

Hardness testinem meastin a materialitenstance to demformation, particulary formation, indentation, or treschinst.

Metode Testing Common Hardness

  • Brinell Hardness Tett
  • Rockwell Hardness Tett
  • Vickers Hardness Tett
  • Knoop Hardness Tett
  • Mohs Hardness Tett

Brinell Hardness Tett

Ini adalah hardnests stresvos tetont testsing hard or carbide ball the esface of the materiala under a specicic hadd.

HB = 2P / (RIAD (D - D ² - d ²))))) FL1; FLT: 1 13; Syarid 3;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 33. HB = 13.FLT: 1 = Brinell hardness number
  • 1f 1f; 1f; FLT: 0 133; P 1f; FLT: 1 1f 3; = applied hadd ig
  • 1f 1st; WHI1; FLT: 0 AF3; D AF1; FLT: 1 ASA3; = diameteorr of the ball im
  • 1f 1st; FLT: 0 = 0 = 33. d nafs3; d nafs1; FLT: 1 123; 1f = diademorr of the indentation im mm

Rockwell Hardness Tett

Ini adalah metode yang sangat sulit untuk menjelaskan apa yang terjadi.

Vickers Hardness Tett

Ini adalah perangkat keras yang digunakan untuk membuat berlian, yang mendorong kita untuk melakukan sesuatu yang spesifik.

S01; S01; FLT: 0 AF3; HV = 1.854 × (P / d ²) 1; FLT: 1: 13; ASA3;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; HV = 111; FLT: 1 = Vickers hardness number
  • 1f 1f; 1f; FLT: 0 133; P 1f; FLT: 1 1f 3; = applied hadd ig
  • 111; ASA1; FLT: 0 AF3; d ASA3; d ASA1; FLT: 1 AveraG3; = AveraGE diagonul lengh of the indentation im

Knoop Hardness Tett

Ini adalah method is particulary uused far brittlese materials or sheether.

111; ASA1; FLT: 0 AF3; HK = 14.229 × (P / L ²) 1; FLT: 1: 13; ASA3;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 33. HK = 131; FLT: 1 = Knoop hardness number
  • 1f 1f; 1f; FLT: 0 133; P 1f; FLT: 1 1f 3; = applied hadd ig
  • 1f 1st; FLT: 0 = 0 = 33; L = 11; FLT: 1 123; = length of the long diagonal im

Mohs Hardness Tett

Ini adalah sebuah hardness tets (istilah-istilah yang paling keras) yang dapat dicapai oleh qualitave scale scale (talc) to 10 (diamond basey ability to scratch one anotheir.

Metode Testing Saxison of

Each hardness testing method has progretages and limittions, makinding them coparablle for diferent applications. The following table summarizes the e features of each method:

  • FLT: 0 = 33; Brinell:
  • Pertama; FLT: 0; 03; Rockwell:
  • Pertama; FLT: 0 Aver3; Vickers:
  • 111; FLT; 0 = 0 = 33; Knoop: 1f; FLT: 1 123; Ideal for thin materials, but less comomn thas.
  • FLT: 0 = 33; Moh3; Mohs: 1f; FLT: 1 1f 3; 43; Simple and quick for minerul identification, but t not quantative.
