It does not mention corrosion resistance or thermal fatigue at all, but a copper-based alloy with good dimensional stability and thermal conductivity could be an interesting alternative to Inconel alloys for heat exchanger tubes.
- xxs 1y agoThe article mentions one year test at 800C being annealed. I suppose you meant thermal cycles?
- Beretta_Vexee 1y agoEnglish is not my native language. I am referring to fatigue caused by thermal cycling. Annealing for one year is done to test the chemical stability of the alloy and ensure that there is no migration or segregation of alloy elements. There may be unstable hydrodynamic phenomena in a pipe or heat exchanger, which generates a large number of thermal cycles. Such as the instability of a vortex in a mixing or heat exchange zone. This is a different ageing mechanism. It is very complicated and time-consuming to test in the laboratory.
