Question

Temperature depended ductile-to-brittle transition can be determined by -

• A. tensile testing
• B. Charpy impact testing
• C. roughness testing
• D. Brinell hardness testing

Answer 1

Answer:

B. Charpy impact testing

The toughness test is conducted to study material behavior under dynamic load conditions. Two testis are there- Charpy Impact test and Izod impact test. Charpy impact testing determines temperature-depended ductile-to-brittle transition. A universal testing machine is used to test tensile and compressive strength of materials.
