Question

For each of the following, indicate whether they are true or false statements:

a) The bending test is used to determine the material properties under shear conditions.

b) Both the material’s toughness and resilience can be obtained from the stress-strain

curves.

c) Fatigue occurs due to static loading for extended periods of time.

d) Substitutional solid solutions occurs between materials having similar sized atoms.

e) Cooling of normalized ferrous materials takes place outside the heating furnace.

Explanation / Answer

a) False. Bend testing a material allows for the determination of that materials ductility, bend strength, fracture strength and resistance to fracture. These characteristics can be used to determine whether a material will fail under pressure and are especially important in any construction process involving ductile materials loaded with bending forces

b) True. The area upto elastic limit gives resilience and area upto fracture point gives toughness in a stress strain curve

c)False. Fatigue occurs due to dynamic loading such as fluctuating stress, alternating stress

d) True. The materials with similar size and comparable elctro affinity and electro negativity can form substitutional solid solutions.

e) True. Normalising is the heat treatment process for ferrous materials. The cooling will take place in Still air (outside furnace) i.e. air cooling
