Quartz is considered one of the most abundant minerals found in the Earth crust that comes second in abundance after feldspar. The term ‘Quartz’ is derived from the Polish words “Twardy” and “kwardy” meaning ‘hard’.
What is the Brinell hardness method? Brinell hardness method is an optical method that works by measuring the intensity of indentation that is caused by an indenting material. Brinell hardness method applies an indenter that is spherical in shape, unlike the Vickers hardness method that applies the use of pyramid-shaped indenter that is pressed on […]
After a metal has been cast in the foundry, it is really necessary to test its hardness. Therefore, after casting metals, the next thing before they are used is a hardness test. After the test, the result reveals the following information, among other things, as regards the material:
With the ever-advancing technology that strives for safety yet efficiency, the outer body of cars is constantly faced with the environmental and human attack that poses as threats to both the life of their users and the life of the car. With the help of the hardness test, manufacturing companies can ensure that the right materials fit the retail requirements of the car.
There is actually no particular method for hardness testing that is absolutely suitable for all materials, since hardness is not an elementary property or characteristic of a material.
The hardness of the bullet depends on the hardness of the lead alloy that is used to manufacture bullets.
This hardness also depends upon the type of pistol that will be used to fire the bullet.
Why test its hardness? It simply must be tested in order to conclude whether or not it is suitable for any sort of task (e.g. could it be used as a building material?). Its durability and hardiness must also be made sure of because that would determine the sort of use the metal could be put to. Let’s move on to how exactly metal hardness can be tested.
The hardness tests are performed on various materials to identify their rigidity.
This application defines the characteristics of the material being tested.
However, those characteristics are not the major property of the material tested.
Hardness is the property of any material to resist deformations to its shape when it is subjected to an external force. Hardness testing is important for technical and engineering applications as it helps to determine the hardness and tensile strength of materials.
