For Rockwell experiment, student has to calculate the depth due to major load (t) through the following formulas for each material tested: .

12. Working Principle 1. SELECTING THE HEAD AND TEST BLOCK Hardened steel and hard alloys like Cast Iron were tested in the Rockwell C scale, using a diamond cone as head and a 150 kg major load. Brass was tested in B scale, using a 1/16” ball as head and a 100 kg major load. Copper was tested in F scale, using a 1/16” ball as head and 60 kg major load. The Rockwell hardness test involves making an indentation on the test material. The indenter is either a conical diamond or a steel ball. Indenter ball diameters range from 1/16 to 1/2 inches and are chosen based on the test parameters.

Using the Rockwell Hardness measurement equipment with diamond braille indenter (Scale C), take measurements from the end at 1/8th inch increments up to 1/2 inch, then 1/4 inch increments up to 2 inches. Round each hardness value to the nearest integer, and discard any values near the end that seem especially low since oxidation has occurred andsl. no. experiment page no. 1. rockwell hardness test 10 2. vickers hardness test 13 3. impact test 16 4. tensile test 21 5. compression test 26 6. shear strength test 29 7. heat treatment 32 8. wear test 35 9. microstructure 39 10. brinell hardness test 43 11. torsion test 46 12. fatigue test 49 13. bending test 53 14. ultrasonic test 56 15.This document describes procedures for harness testing of metallic materials using the Rockwell scale. The Rockwell hardness test measures the indentation made by specific loads on a material's surface. There are different Rockwell scales that use varying loads and indenters depending on the material. The experiment uses a Rockwell hardness tester with a diamond .

A standardized test procedure used to determine the hardenability of steel, the Jominy test (End Quench Test) can be performed using either the Vickers or Rockwell hardness test method. When selecting which to use, you should consider relevant standards, as well as the usual criteria when choosing between different types of hardness test.

ROCKWELL HARDNESS TEST: This hardness test uses a direct reading instrument based on the principle of differential depth measurement. Rockwell testing differs from Brinell testing in that the . Attach the table as an appendix to your lab report!) 2. Using the above converted values, calculate the UTS and YS values using the empirical 5. PAGE 4 Vickers Hardness Test The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a test force of between 1gf and 100kgf. The full load is normally applied for 10 to 15 seconds. The two diagonals of the .ROCKWELL HARDNESS TEST. Lab Report # 4.

Rockwell hardness test is one of the static hardness testing methods using indentation depth as a measuring criterion. Basically, two types of indenter are used; one Diamond spheroconical (Brale) indenter with an angle of 120 O and a spherical tip of 0; second is steel ball indenter with diameters as 1/16, 1/8, 1/4, ½ inches.Table 2 showed that the percent differences for Rockwell Test were smaller than for the Brinell test.
