Copper-nickel-silicon, alloys can be hardened by cold ...

Copper-nickel-silicon (CuNiSi) alloys can be hardened by cold working and an aged (precipitation) heat treatment process. They combine moderate electrical conductivity (up to 60% IACS) with high tensile strength (up to 800 N/mm 2) together with good wear resistance and stress relaxation resistance up to 150 to 200 o C.

Industrial: Design Guide - Overview of Stress Relaxation

Stress relaxation is the time dependent decrease of the stress in a metal under constant strain, such as in a beam with fixed deflection. (The metallurgical processes are similar to those that cause the related phenomenon called creep, where the metal changes geometry over time under a constant stress.) All of the copper alloys are susceptible ...

The age hardening of copper–titanium (Cu–Ti) alloys containing approximately 1–5 wt.% Ti (1–6 at.%. Ti) has been known since the 1930s. The mechanical and physical properties were found to be comparable to the widely used copper–beryllium (Cu–Be) alloys with better high temperature strength and superior stress relaxation behavior.

Multiphysical characterization of FSW of aluminum ...

This work investigates the benefits of having an aluminum (Al) busbar with welded copper (Cu) ends, and evaluates the force relaxation phenomena of a pre-loaded bolt joint on Cu versus Al, under cyclic thermal loading. The results show a force relaxation rate 50% lower in the Cu-bolted joint compared with the one in Al. The core of this research is the weldability analysis of Al-Cu …

Bolted Joint Design - Fastenal

Proper amount of tensioning of the bolts is vital. With too little clamping force, the joint may loosen. If the joint is exposed to cyclical loads, too little clamping force can shorten the bolt's fatigue life. Too much clamping force can also cause severe problems. By over-tightening the bolt, one may exceed the proof load of the bolt.

A bolt is a type of threaded hardware fastener that is used to position two workpieces in specific relation to each other. Bolts come in several configurations for their application and specification variances. Since the terms "bolt" and "screw" were in use before the advent of easily-produced helix fasteners, they are often synonymous.

Mechanisms of Stress-Corrosion Cracking

For example, the SCC of copper alloys, tradition­ ally referred to as season cracking, is usually due to the presence of ammonia in the environment, and chloride ions cause or exacerbate cracking in stainless steels and aluminum alloys. Also, an en­ vironment that causes SCC in one alloy may not cause it in another. Changing the temperature, the

Industrial: Design Guide - Fatigue Strength - Copper

A fatigue failure is one in which the metal fractures because it is subjected to a high number of cycles at a stress below the metal's yield strength. Fatigue occurs because micro cracks develop on the metals surface when it is cyclically stressed. With repeated bending these cracks propagate through the metal thickness to a point where the ...

Stress corrosion cracking - Wikipedia

Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature.SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to a small number of chemical environments.
