    查看更多>>摘要：SA508Gr.4 N steel is commonly used in nuclear pressure vessels.The current study discloses the impact of austenitizing temperature on its martensitic transformation.Various austenitizing temperatures were employed to examine the martensitic transformation at different experimental conditions.The character-istics of grain boundaries,microstructure,transformation kinetics,and crystallography of the martensitic phase following the austenitizing process and martensitic transformation were analyzed.Austenitizing temperatures had minimal effects on the critical temperature of the austenitizing phase transition.How-ever,an increase in austenitizing temperature resulted in larger grain sizes.The phase composition pri-marily consisted of lath martensite,accompanied by a small amount of residual austenite(RA).As the austenitizing temperature increased,the temperature of martensite-start temperature(Ms)initially de-creased and then increased.On the other hand,the temperature of martensite-finish(Mf)showed no significant sensitivity to changes in the austenitizing temperature.Moreover,the average size of the lath martensite structure was increased,and there was an increased tendency for variant selection as the austenitizing temperature increased,and the combination of specific orientation relationships appeared.This study is very valuable for revealing the microstructure evolution at different temperatures.

    查看更多>>摘要：With the rapid advancement of the intelligent era,intelligent electromagnetic interference(EMI)shielding devices are receiving more and more attention due to their advantages in environmental self-adaption re-sponse.Accordingly,appropriate EMI shielding materials are crucial to blocking harmful electromagnetic radiation and passing serviceable electromagnetic waves.Smart EMI shielding materials that can dynam-ically adjust their EMI shielding effectiveness(SE)in response to specific application requirements and environmental changes are extremely advantageous in both military and civil areas.To date,materials with adjustable EMI SE for various responses have been developed.This review pays special attention to smart materials with tunable EMI SE.The design strategies,mechanism and recent progress of smart EMI shielding materials are discussed together with different stimuli responses,including compression strain,tensile strain,chemical reagent,shape memory,phase transition and crossover angle change-induced re-sponses.The review ends up to discuss challenges and perspectives for smart EMI shielding materials.
