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...
متن کاملThe Effect of Low Dose-Rate Irradiation on the Microstructure of 304 Stainless Steel*
Changes in mechanical and corrosion properties caused by the development of radiationinduced microstructure have relevance to the aging and lifetime extension of light water reactors (LWR’S). However, much of the current data related to microstructural development in irradiated metals are generated from studies carried out at much higher dose-rates than encountered in LWR’S. An opportunity exis...
متن کاملStudy of creep cavitation in a stainless steel weldment
A study of creep cavities near reheat cracking in AISI Type 316H austenitic stainless steel headers, removed from long-time high temperature operation in nuclear power plants, is reported. It is shown how application of scanning electron microscopy (SEM), cryogenic fractography and small angle neutron scattering (SANS) can be applied, in a complementary way, to observe and quantify creep cavita...
متن کاملFactors Affecting Friction Coating on Stainless Steel 304
Low carbon steels are widely used for structural applications because of its ease in fabrication and the moderate strength it posses. However, its pure corrosion resistance at normal atmosphere is a matter of serious concern.
متن کاملInfluence of nitrogen ion implantation on the nanostructure and corrosivity of Ni/stainless steel substrates
Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...
