Objective :

To determine the indentation hardness of mild steel, brass, aluminium etc. using Vickers hardness testing machine.

Apparatus used :

Vickers hardness testing machine.

Type of indenter used is diamond cone indenter with square based pyramid shape.

Select the type of material :

Aluminium

Brass

Mild Steel

Selected Material :

Load Applied :

The selected specimen is placed on a supporting table and the height is adjusted by rotating hand wheel.

Specimen is in position

Move the mouse cursor on
the wheel to adjust
specimen height

The load to be applied on a specimen is set by adjusting the knob.

The time up to which load has to be applied for the specimen is adjusted.
