RELAXATION
• The ability to keep the same spring force under a certain deformation over a long time – very critical in electrical clamps where the wire is spring load clamped for a long time, maybe 50 years or more
RELAXATION
INFLUENCING FACTORS
• Stress level • Temperature
PARAMETERS TO OPTIMIZE
• Static strength
• Structure obstructing slip
− Precipitation hardening − Duplex structure − Thermal stability
