Vickers Hardness Test Quiz

What is the main principle behind the Vickers hardness test?

• Applying a rotating force to the test piece

• Using a laser to measure surface hardness

• Pressing a pyramid-shaped diamond indenter onto the test piece

• Pressing a spherical indenter onto the test piece

What is the shape of the Vickers indenter used in the hardness test?

• Cylindrical

• Spherical

• Pyramid-shaped

• Conical

What is the first step in preparing the testing machine for the Vickers hardness test?

• Adjusting the height of the support table

• Inserting the Vickers indenter into the mounting device

• Placing the test piece on the support table

• Rotating the microscope lens into position

How is the test piece positioned for the hardness test?

• By rotating the microscope lens

• By moving the test piece around on the support table

• By pressing the start button

• By adjusting the height of the support table

What happens after the start button is pushed in the Vickers hardness test?

• The test piece is moved to the correct spot

• The hardness value is displayed on the screen

• The microscope lens rotates into position

• The diamond pyramid indenter touches the test piece surface

What is the purpose of the control knob during the measurement of the indentation?

• To adjust the height of the support table

• To place measuring lines at the corners of the indentation

• To rotate the microscope lens

• To press the start button

What is displayed on the screen after the indentation is made?

• The length of the diagonals

• The hardness value

• The magnified indentation

• The test force value

How is the Vickers hardness value calculated?

• By dividing the test force by the length of the diagonals

• By multiplying the test force by the area of the indentation

• By dividing the test force by the area of the indentation

• By adding the test force to the area of the indentation

What is the final step in the Vickers hardness test process?

• Rotating the microscope lens into position

• Pressing the input key to calculate the hardness value

• Placing the test piece on the support table

• Adjusting the height of the support table

Where is the Vickers hardness value displayed after calculation?

• Bottom left corner of the screen

• Top right corner of the screen

• Bottom right corner of the screen

• Center of the screen
