Brinell hardness uses a 10mm steel ball indenter and applies a load for 10-30 seconds to measure indentation diameter. Vickers microhardness uses a small diamond pyramid indenter under low loads of 1-1000gf to measure indentation diagonals. Each method has advantages like suitability for different materials, load ranges, accuracy, and disadvantages like sensitivity, suitability for size or hardness ranges.

Brinell hardness testing involves indenting a material's surface with a hard steel or tungsten carbide ball under a heavy load and measuring the diameter of the indentation. The Brinell hardness number depends on the applied load and resultant indentation size. Rockwell hardness testing directly provides a hardness value based on measuring the depth of indentation from both a minor and major applied load.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Networking is a telecommunications network that allows computers to exchange data. In
computer networks, networked computing devices pass data to each other along data
connections. Data is transferred in the form of packets. The connections between nodes are
established using either cable media or wireless media.
This is an overview of my current metallic design and engineering knowledge base built up over my professional career and two MSc degrees : - MSc in Advanced Manufacturing Technology University of Portsmouth graduated 1st May 1998, and MSc in Aircraft Engineering Cranfield University graduated 8th June 2007.
2. Ensure quality
Test properties
Prevent failure in use
Make informed choices in using materials
Factor of Safety is the ratio comparing the actual stress on a material and the safe useable stress.
3. Mechanical tests – the material
may be physically tested to
destruction. Will normally specify a
value for properties such as strength,
hardness, toughness, etc.
• Tensile Test
• Flattening Test
• Flaring Test
• Hardness Test
• Bend Test
• Impact Test
• Creep Test
Non-destructive tests (NDT) –
samples or finished articles are
tested before being used.
• Visual Inspection
• Penetrant Testing
• Magnetic Particle Testing
• Ultrasonic Test
• Radiography Test
• Eddy Current Test
• Long Range Ultrasonic Test
• Infrared Thermography
4. Tensile Testing
Uses an extensometer to apply measured
force to an test specimen. The amount of
extension can be measured and graphed.
Variables such as strain, stress, elasticity,
tensile strength, ductility and shear strength
can be gauged.
Test specimens can be round or flat.
5. The tube shall be flattened between two plain parallel and rigid
platens which extend over both the full length and the width
after flattening of the test specimen. Flattening is to be
continued until the distance between the platens, measured
under load, is not greater than the requirements
The flattening shall be continued until the specimen breaks or
the opposite walls of the pipe meet.
6. Expansion the end of the tube symmetrically by means of a
hardened conical steel mandrel having a total included angle of
60 deg. The mandrel is to be forced into the test specimen until
the percentage increase in the outside diameter of the end of the
test specimen is not less than the value given in the specification
requirements.
7. •Hardness is the ability to withstand indentation or
scratches
•Brinell hardness test-Uses ball shaped indentor.
•Vickers hardness test-Uses square shaped pyramid
indentor.
•Rockwell hardness test- Rockwell B (ball) used for soft
materials , Rockwell C (cone) uses diamond cone for
hard materials
8. Bend Test
Bend tests deform the test material at the midpoint causing a concave surface or
a bend to form without the occurrence of fracture and are typically performed to
determine the ductility or resistance to fracture of that material.
9. •The purpose of impact testing is to measure an object's ability to resist high-
rate loading. It is usually thought of in terms of two objects striking each other
at high relative speeds.
•There are two main forms of impact test, the Izod and the Charpy test.
•This is an important issue for materials used in low temperature service
because many steel alloys undergo a phase transition from a ductile state to a
brittle state at temperatures well above -320F. Impact testing is one means of
assessing the extent to which a material is brittle or ductile.
11. Dye penetrant testing
Dye penetrant inspection (DPI), also called liquid
penetrant inspection (LPI) or penetrant testing
(PT), is a widely applied and low-cost inspection
