Alloy 600 weld metal C and Nb contents FEM analysis stress Stress corrosion cracking y 'phase
The SCC susceptibility of the weld metal was evaluated from the maximum depth and number of cracks occurring during the CBB (Creviced Bent Beam) test in high temperature pressurized water using plate specimens cut from shielded metal arc weld metals. When the specimen received a heat treatment consisting of stress relief annealing (SR) for 72 ks at 893 K and subsequent ageing (LTA) for 720 ks at 673 K, however, the significant influences of the increases in C and Nb contents on the SCC susceptibility were...

Corrosion Liquid droplet impingement Nuclear reactor Pipe wall thinning Stainless steel Wear
In this paper, to study the wear properties of the pipe materials for the nuclear power stations, a high temperature impact fretting testing was carried out. Employing two piezo actuators, impact fretting test rig can generate impact fretting under various impact loads, fretting amplit udes and frequencies. It also enables us to control water temperature, dissolved oxygen and water pressure. AISI type 304 stainless steel, which is used as a pipe material in nuclear power stations, was used as specimens. Al...

Corrosive wear Impact fretting Liquid droplet impingement erosion Pipe wall thinning Stainless steel
In order to study the wear properties of the pipe materials for the power generating plants, impact fretting wear tests of AISI304 disks against Al2O3 balls and AISI304 balls were carried out in high temperature pure water. SEM, EPMA, 3D-profilometer and nano-indenter were used for observation, analysis and measurement of wear scars. The maximum wear depth of the disk increased with an increase in water temperature and decreased with an increase in impact frequency below 80°C. However, the maximum we...
