“…3(A), it can be seen that the capacitive resistance arc from the highfrequency region to the low-frequency region has a circular shape, which is related to the dispersion effect of the passivation lm with semiconductor properties [10,11]. It is related to the electron migration exchange process at the passivation lm/solution interface, and its diameter is proportional to the charge transfer resistance (R ct ) [12,13], so the larger the diameter of the capacitive arc, the larger the impedance and the better the corrosion resistance. As shown in Fig.…”

321 stainless steel has high room temperature strength and oxidation resistance. It is investigated that the corrosion resistance of 321 stainless steel in hydrochloric acid solutions containing different concentrations of NaCl in the research. The alloy is mainly composed of austenitic stainless steel. The results of electrochemical tests were analyzed, and it was confirmed that NaCl could promote the corrosion of 321 stainless steel, but the corrosion would be suppressed to a certain extent when the NaCl concentration reached 0.10 mol/L. The research results can provide a reference for the corrosion resistance improvement research of 321 stainless steel.

Technologically important Oxide Dispersion-Strengthened steels are synthesized using ZrO2 as a dispersion strengthener instead of conventionally used Y2O3. Powder metallurgical route followed by spark plasma sintering is adopted for synthesizing the material. Detailed microstructural characterization revealed a fine-grained microstructure with finer dispersoids in as-sintered and normalized condition. The stable microstructure is found to be retained even after subjecting the samples at 973 K for as long as 1000 h for long-term thermal aging trials, indicating at a possible superiority of this material over the conventional Oxide Dispersion-Strengthened steels. The yield strength is calculated by making use of microstructural parameters and predictive models, both of which shown a good agreement. Mechanical property analysis through hardness measurements was correlated with microstructural observations and compared with the conventional Oxide Dispersion-Strengthened steels. The collective results indicate ZrO2 as a potential alternate dispersoid for strengthening steel and future scope for vast exploration.
