Influence of remelting and annealing treatment on

Feb 15, 2019 · Corrosion resistance increases after remelting and annealing treatment and the annealed HEA shows the best corrosion resistance, which illustrate that annealing treatment has more positive influence on corrosion resistance than remelting treatment. The increase of corrosion resistance can be contributed to the transform of alloy microstructure. Influence of annealing treatment on microstructure and The electrical corrosion morphology indicated that, the corrosion was firstly at the distortion area and the crevice corrosion mechanism played an important part. Based on these results, processes active during annealing treatment are kinetically dependent and strongly influenced by the annealing treatment temperature. Influence of annealing heat treatment on pitting corrosion The effect of annealing heat treatment on pitting resistance of stainless steel type 316L has been studied using Tafel polarization and ASTM G150 for estimating of the pitting potential and CPT, respectively. The materials were tested in 3.5% NaCl solution. The chemical composition of the material was analyzed via optical emission spectrometry. Influence of annealing heat treatment on pitting corrosion Influence of annealing heat treatment on pitting corrosion resistance of stainless steel type 316L July 2014 Metallurgical and Materials Engineering 20(2):97-105 Influence of solution annealing temperature and cooling Jan 29, 2015 · The results indicate a large influence of the solution treatment temperature, duration and cooling rate on passivation behavior and pitting corrosion resistance. Higher solution annealing temperatures increase the amount of chromium and carbon dissolved in solid solution resulting in easier passivation and higher hardness. Influence of Homogenization Annealing of AZ91 on Feb 12, 2008 · A homogenization annealing (HA) heat treatment is proposed for property enhancement for AZ91; HA for 10 h at 410 °C caused an improvement in hardness, ultimate tensile strength and ductility without loss of corrosion properties. The influence on the corrosion behavior of the microstructure was studied. Effect of annealing treatment on microstructure evolution The influence of annealing temperature on the pitting corrosion of a super-duplex stainless steel (SDSS) with mischmetal addition was investigated in chloride solution by critical pitting MICROSTRUCTURE ANALYSIS, MECHANICAL 2.3.3(g) Influence of post-annealing treatment after cryorolling process 31 4.5 Effect of pre-annealing treatment on cryorolling of Al 1100 alloy 86 4.8.3 Effect of heat treatment on corrosion behaviour 151 4.9 Summary of result and discussion 152
