Resilience

A material's capacity to absorb energy before breaking. This value can be determined by a Charpy test.

Charpy test

Resilience test used to characterize a material's energy absorption capacity prior to flexural failure. It consists in striking a specimen of the material to be tested, resting on two supports, with a pendulum of mass dropped from a given height, to enable comparison and reproducibility of results. The height at which the pendulum rises after impact is used to determine the energy required to break the specimen.

Inclusion

Casting or welding defect. A metallic or non-metallic particle foreign to the part's base material, trapped in the part during cooling.

Crack

Metallurgical defect. This is a fine notch resulting from the manufacturing process. It can occur during forming operations, such as casting, or during processing (machining,...
