What does malleable mean?

• able to bend
• will break easily
• can be used for wire
• is shiny

Hardness of metal means that it is ...

• resistant to corrosion
• resistant to bending
• resistant to abrasion/permanent deformation
• resistant to rupture

Which of these are non destructive testing processes?

• Crack detection

• Hardness testing

• Tensile testing

• Conductivity testing

Which of these are true?

• Hardness is tested using a standard machine to make an hole in the surface of the material

• Hardness is tested using a standard machine to make an indentation in the surface of the material

• The width of the hole determines the hardness of the material

• The size of the indentation determines the hardness of the material

Which of these are true about hardness testing?

• Brunell Hardness is a type of testing to force a sphere of metal into a surface

• Vickers Hardness is a type of testing using a diamond indenter

• Hardness testing is often carried on materials after heat treatment

• Hardness tests are measured using a combination of numbers and letters to create a value e.g. 3mm Sheet Steel could have a measurement of Rockwell C 71

• Hardness testing is often carried out on materials before heat treatment

Which of these are not true about non-destructive testing

• It is generally carried out on unfinished products

• It is generally carried out on finished components of products

• It is generally carried out on unfinished components of products

• It is generally carried out on finished products

Which of the following are not non-destructive testing methods?

• Bounce testing

• Ultrasonic testing

• Dye penetrant inspection

• Visual inspection

• X-ray testing

Which of the following tools are not used when performing a visual inspection test?

• Boroscope

• Stethoscope

• Mirrors

• Endoscope

• X-rays
