Investigating the Effect of Secondary Phase Precipitation on Pitting Corrosion Behaviour of 26.54% Cr Super Duplex Stainless Steel

Effect of annealing time on the static and accelerated corrosion behavior of medium manganese steel

Effect of stress on the corrosion behavior of a near-β titanium alloy in 3.5wt.% NaCl solution

The corrosion behavior in 3.5wt.% NaCl solution under different stresses of a near-β titanium alloy with three microstructures, single-phase β (CS1), fine α+β (CS2), and coarse α+β (CS3), was investigated. Electrochemical tests showed that the corrosion resistance in the unstressed condition followed the order of CS1 >...

Effect of Thermal Aging on Stress Corrosion Cracking in High Temperature Water for Cast Duplex Stainless Steel Used in Primary Coolant Pipe

The Z3CN20.09M cast duplex stainless steel (CDSS) for primary circuit main pipelines in second generation nuclear plants was subjected to accelerated thermal aging at 450°C for 5000 h (~64.7 equivalent service years at 290°C cold‑leg temperature), and its stress corrosion cracking (SCC) behavior was investigated. Slo...

Evaluation of hot corrosion performance of 904L stainless steel through corrosion-enhanced erosion testing at elevated temperature (650 °C)

The hot corrosion-enhanced solid particle erosion behavior of super austenitic stainless steel 904L was investigated at 650 °C. Cyclic corrosion tests (25 hours in 5-hour cycles) employed a Na 2 SO 4 –NaCl (3:1 wt%) salt deposit of 4.0–4.5 mg cm −2 . Salt-coated specimens obeyed a parabolic rate law (k p  = 1...

Effect of direct aging on the microstructure and sustainable milling performance of L-PBF 17-4 PH stainless steel

This study investigates the influence of direct aging (DA) and cooling/ lubrication strategies on the milling performance of 17–4 PH stainless steel (SS) fabricated via laser powder bed fusion with a comparative assessment against commercially obtained 17–4 PH SS. Direct aging was performed at 580 °C for 1, 2, and 3 h...

Effect of Shot Peening on the Corrosion Behavior of 304 Austenitic Stainless Steel in Molten Solar Salt

The effect of shot peening on the corrosion behavior of 304 austenitic stainless steel in molten Solar Salt (60 wt% NaNO 3  + 40 wt% KNO 3 ) at 550°C was studied. Shot peening markedly improves the corrosion resistance of 304 austenitic stainless steel. Electrochemical tests show a 35.2% reduction in corrosion...
