Asnt Level 3 Basic Materials & Processes Questions With Correct Answers

Fracture is a type of material failure. Of the following which is another type of material failure? CORRECT ANSWER Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? CORRECT ANSWER Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: CORRECT ANSWER NDT involves indirect tests related to some other quality or characteristic of material. What are the functions of NDT? CORRECT ANSWER Identifying and sorting of material. Identifying of material properties. Ensuring absence of faults or defects that could cause a part to fail. An important basis for the success of fracture control design procedures is: CORRECT ANSWER The need to ensure that unexpected flaws of some critical size are not present when the component enters service. If properly used, NDT can assist in fracture control by: CORRECT ANSWER Providing an accurate evaluation of the number and type of discontinuities that exist in a material . A statement that a particular experiment produced a 0.9 probability of detection with a 95% confidence level means that: CORRECT ANSWER There is a 5% probability that the probability of detection is overstated. Most solid metals and plastics that have reasonable strength at room temperature are called: CORRECT ANSWER Engineering materials. Material properties, as used in design, are most frequently determined by: CORRECT ANSWER Materials testing. Even at the early stages of product planning, NDT should be considered because: CORRECT ANSWER The design of the part should permit easy access to critical areas for later inspection. which of the following material properties are of most concern if corrosion resistance is essential? CORRECT ANSWER Chemical properties.
