“…It was worth noting that the highest tensile residual stress of C3 and D3 specimens can reach over 1000 MPa, which unexpectedly exceed the tensile strength of 304L and 316L SSs significantly. According to previous studies, this can be attributed to the fact that the martensitic phase transformation could occur during milling operations . The D3 specimen has the highest residual stress reaching to 1053.6 MPa, while it was tiny for the mechanical polished specimens such as A0, C0, and D0.…”

The stress corrosion cracking (SCC) behaviors of Z3CN20.09M, 304L, and 316L austenitic stainless steels (SSs) after milling operation in boiling magnesium chloride solution were investigated by scanning electron microscopy (SEM), X‐ray diffraction, and 3D profilometer. The experimental results indicated that the roughness and residual stress increased with increasing feed rate of all specimens. The depth of deformation layer after milling operation reached about 150 µm shown as persistent slip bands (PSBs) were formed, leading to hardness enhanced obviously. After SCC tests in boiling magnesium chloride solution, the crack densities increased with increasing feed rate of the Z3CN20.09M SS specimens. However, the crack densities decreased as well as the intergranular (IG) cracking percentages increased with increasing feed rate of the 304L and 316L SS.

“…The reason of the Rc instability is probably caused by the oxidation on the surface of CuCrZr pin, which behaves like insulation layers between two electrical contact surfaces. The oxidation phenomenon of CuCrZr had been well researched and the oxidations are Cu 2 O and CuO [26,27]. As Fig.…”

Radio-Frequency (RF) contacts are key components on the International Thermonuclear Experimental Reactor (ITER) Ion Cyclotron Resonance Heating (ICRH) antenna, and these components are facing big challenges such as 2 kA operation current load and intensive sliding under up to 250 C in high vacuum. Stainless steel (SS) 316L and CuCrZr are most likely to be applied as base materials for the conductor and the RF contacts louvers. To evaluate the performance of the selected materials, their electrical and tribological behaviors have to be studied. A multifunctional tribometer which can mimic the ITER ICRH RF contacts' relevant working conditions was designed and built in CEA. The contact resistance (Rc) and coefficient of friction (CoF) of CuCrZr-316L pair were researched on this tribometer.
