1.1 workshop tests Flashcards
What is the workshop tensile test
A material is clamped and a mass is added to the other end of the material. The greater the tensile strength the less t will bend
What is the workshop toughness test
A material is clamped into a vice and then hit with a hammer (The more bent the material the lower the toughness)
What is the workshop hardness test
A dot punch is placed on a material and then impacted (The larger the indent the less hard the material is)
What is the corrosion workshop test
A material is placed outside to see if it can withstand environmental damage
What is the electrical conductivity workshop test
Probes at either end of the material tests the resistance of the material
What is the thermal conductivity workshop test
The material is heated at one end and then a stopwatch measures how long it takes for the material to heat at the other end
What is the industrial tensile test
The material is placed into a tensometer which applies a force stretching the material (The resistance of the force depends on the tensile strength)
What is the industrial toughness test
A Charpy impact test uses a swinging pendulum that impacts a material to test for toughness where the lower the pendulum swings after the impact the more force the material absorbed (More tough)
What are the 3 industrial hardness tests (Name)
Rockwell, brinell, vickers
What are the 3 industrial hardness tests (Explain)
Rockwell - The diamond indentor makes a small and large load and the diffirence between the 2 measures the hardness
Brinell - The steel ball indents and the diameter of the hole measures the hardness
Vickers - The diamond pyramid indents the material and the smaller the indent the harder the material
What is the Xray test
An Xray is passed through a material and the image is projected onto a screen to display faults in the material
What is the ultrasonic test
A transducer makes sound that pass through the material and bounce back to create a display of the material for faults
What is the thermal conductivity industrial test
2 plates are put around the material the heat increases at a steady rate and the heat transfer is measured
What is the electrical conductivity test
The material is placed between 2 copper blocks and wires measure the materials current and voltage to then find its resistance
What is the industrial ductility and malleability test
The material is placed in a bending machine and bent with crack on the outer side meaning ductility and the inside meaning malleability
