Localised-in-the-edge oxidation of four AISI 430 alloys was investigated after an industrial bright annealing process. The oxidised surface each specimen characterised by X-ray photoelectron spectroscopy (XPS), Raman-spectroscopy and SEM. results showed that the selective Cr Mn took place at coil edges 430. This led to formation oxide scale based on Cr2O3 MnCr2O4. On other hand, Cr(OH)3 MnOOH i...

Ferritic stainless steels have been widely used to substitute austenitic because of their lower cost and higher deep drawing capacity. However, failures, such as shear fracture, observed in parts with small radii during the process applications where both bending stretching occurs. Conventional techniques, failure criterion consideration, finite element method, forming limit diagram, are unable...

In this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (AISI 316) and ferritic (AISI 430) stainless steel substrates have been investigated using torch technique. The effects of substrate surface preparation has also been studied. The quality of coatings produced has been examined using optical and scanning electron microscopy, X-ray diffraction, Raman spectros...

Metallic composite coatings with ceramic particles can be used to improve the mechanical and corrosion properties of steel. In the present research, Ni-ZrO2-TiO2 composite coating was fabricated on AISI 430 stainless steel through the electrodeposition method. The effect of the current density of electroplating (15, 17, 20, and 23 mA.cm-2)was investigated on the...

In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of welds. Also, vibrational sample magnetometry was used for characterizing magne...
