Development of High Temperature Multiaxial Creep Properties Evaluation Method for Type 304 Stainless Steel using Miniature Cruciform Specimen

Compressibility of 304 Stainless Steel Powder Metallurgy Materials Reinforced with 304 Short Stainless Steel Fibers

Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...

Magnetic Properties of Metastable 304 Stainless Steel with Bcc Structure

Ordinary 304 stainless steel has a fcc structure and is non-magnetic at room temperature. By using a vapor quenching method, we have fabricated single-phase metastable bcc 304 stainless steel which is strongly ferromagnetic with a magnetization of 130 emu/g and a Curie temperature in excess of 550 OC. Upon subsequent annealing above 550 OC, the metastable bcc state transforms back into the usua...

Corrosion Performance and Tribological Properties of Carbonitrided 304 Stainless Steel

Effect of nitriding temperature on the nanostructure and corrosion properties of Nickel coated 304 stainless steel

Nickel films of 150 nm thickness were deposited on 304 stainless steel and post annealed under flow of nitrogen at different temperatures. The prepared samples were corrosion tested in 1.0 M H2SO4 solution using potentiodynamic polarization technique. Crystallographic and morphological structure of the samples were analysed by X-ray diffraction XRD and atomic force microscopy AFM respectively b...

Measurement of local creep properties in stainless steel welds

A high temperature measurement system for creep deformation based on the digital image correlation (DIC) technique is described. The new system is applied to study the behaviour of a multi-pass welded joint in a high temperature tensile test and a load controlled creep test at 545°C. Spatially resolved tensile properties and time dependent creep deformation properties across a thick section typ...
