Professor Lindsay Corneal October 27 2016 Abstract The purpose of this experiment were to utilize the hardness as an index of mechanical properties to relate the mechanical properties of ferrous and metal to.

The results obtained showed that the aluminum sample HB of 1173559 kgmm2 has a higher hardness than the steel sample HB of 11060855 kgmm2. In this lab we will be determining the indentation hardness of four different metals Aluminum 7075 T-24 Aluminum 6061 T-6 AISI Steel 1045 and AISI Steel 1018. The purpose of the following experiments is to study the hardness of different types of materials and to understand the significance of this property in materials.

LABORATORY REPORT NUMBER 002. Cavity diameter measured from the Brinell hardness machine is converted into the Brinell hardness number by the help of following formula. The Vickers hardness test was developed in 1921 by Robert L.

Hardness values for aluminum. One of the better known is the Spencer Bierbaum instrument. A Keep the loading and unloading lever at position A which is unloading position.

The Vickers hardness test follows the Brinell principle in that an indenter of definite shape is pressed into the material to be. The materials and the aforesaid property have significant use in civil engineering. GROUP A SUB GROUP A2.

D is diameter of the ball used for indentation. Di ameters of the different Balls used in Brinell Hardness Test. Rockwell B Test Brinell 10500 Hardness Test Average 997 2275 Conversion table value 95 220 Table.

The purpose of the following experiments is to study the hardness of different types of materials and to understand the significance of this property in materials. As seen in the theory previously presented this implies that aluminum is more resistant to. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of the material.

The materials and the aforesaid property have significant use in civil engineering. A small dent or a scratchRockwell and Brinell are popular hardness testing methods In a hardness test a small indenter is forced into the surface of a material to be tested and the size or depth of the resulting indentation is measures which in turn is related to a hardness number. Subsequently the diameter of the impression on the sample was measured by a vernier caliper and then repeated three times to reduce the error in the experiment and the average value was obtained.

Type of Indentor used in the Three Different Scales of Rockwell Hardness Test. HB 2F πD D- D-d Here. After that the diameter of the indentation d mm is measured when the load is removed.

Where h mm is the depth of indentation D mm is the diameter of the ball. 1 Tables recording the readings and hardness number of all the specimens refer to the Log Sheet 2 Plot of Hardness v Carbon Content for the Plain Carbon Steel for each hardness test. The materials and the aforesaid property have significant use in civil engineering.

HARDNESS TESTING PURPOSE The purpose of this exercise is to obtain a number of experimental results important for the characterization of the mechanical properties and performance of materials. Different Types of Hardness Testing Methods. INDENTATION OF A METAL BY A BALL.

The hardness of materials are test by pressing a steel ball or tungsten carbide ball for a time of 10 to 15 seconds into the surface of specimen by a standard load F kgf. The hardness test is a mechanical test for material properties which are used in engineering design analysis of structures and materials development.
