Selecting metal materials - Implementation and players

The functions required of a mechanical part in service can be very diverse:

• resistance to static forces, mostly in the field of reversible (elastic) behavior, at room temperature, at lower temperatures (cryogenic applications) and more often at higher temperatures ;

• resistance to dynamic stress (fatigue) [97];

• resistance to Hertzian pressure, friction and wear ;

• service life, operating reliability ;

• resistance to the environment (other parts in contact, atmosphere, humidity, etc.) ;

• more specific functions: transmission of heat, electric current, magnetic field, resistance to radioactivity.

In addition, the technical imperatives of lightness, recyclability, ease of assembly, shape, low energy costs and suitability for manufacturing...
