In the present work, the effects of different casting parameters including pouring temperature and cooling rate on stainless steel structures and mechanical properties of heat resistant alloy (HH) were studied. Mo nanoparticles were synthesized through sol-gel method and were coated on the stainless steel device using spin-coating method. The effect of coating layer on the device was studied by...
Transient liquid phase bonding of UNS S32750 super duplex stainless steel to AISI 304 austenitic stainless steel using BNi-2 interlayer was carried out at 1050 oC for 45 min. Microstructure analyses of the joint were carried out using optical microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. Microhardness indentation and shear strength test were performed to as...
Performance Study on Aisi316 and Aisi410 Using Different Layered Coated Cutting Tools in Cnc Turning
Stainless steel (SS) is used for many commercial and industrial applications owing to its high resistance to corrosion. It is too hard to machine due to its high strength and high work hardening property. A surface property such as surface roughness (SR) is critical to the function-ability of machined components. SS is generally regarded as more difficult to machine material and poor SR is obta...
A significant amount of research has been reported on stainless steel tubular sections, while studies I- and C-sections remain relatively limited. This paper presents a comprehensive numerical study the response subjected to minor axis bending, with outstand flanges stress gradients. Numerical models are developed validated against test data austenitic sections under bending. Subsequently, para...
Residual stresses impact on a wide variety of industrial sectors including the automotive, power generation, industrial plant, construction, aerospace, railway and transport industries, and a range of materials manufacturers and processing companies. The X-ray diffraction (XRD) technique is one of the most popular methods for measuring residual stress [1], used routinely in quality control and ...
در این تحقیق، تولید فولاد زنگ نزن نانوساختار 301 با استفاده از عملیات ترمومکانیکی نورد سرد سنگین و آنیل مورد مطالعه قرار گرفت. در این فولاد، آستنیت با انجام نورد سرد به مارتنزیت (strain-induced martensite) تبدیل می شود. با بازگشت مارتنزیت تغییر شکل یافته به آستنیت طی فرایند آنیل و با انتخاب دما و زمان مناسب می توان فولادی با اندازه دانه بسیار ریز تولید کرد. به همین منظور پارامتر های آنیل فولاد ...
Stainless steel cladding is the formation of an alloy by creating a thin layer of stainless steel on another metal. In this research, a layer of SA240-TP316 austenitic stainless steel was coated on SA516-GR60 steel. Experiments were conducted to compare the mechanical properties of SA240-TP316 and claded SA516-GR60 steel welds in order to investigate the possibility of replacing the SA240-TP316...
This paper reports on the mechanical properties of the dissimilar joints between AISI 316 austenitic stainless steel and St 37 low carbon steel achieved using friction stir welding technique. The welding was carried out by means of rotational speed of 800 rpm and linear speeds of 50,100,150 mm/min. EDS and XRD techniques were employed in order to determine possible phase transformations. Tensil...
Concentrating solar power (CSP) and thermal energy storage (TES) based on molten salts still lacks economic feasibility, with the material investment costs being a major drawback. Ferritic stainless steels are comparatively cheap class of materials that could significantly contribute to cost reductions. The addition aluminum ferritic steel can result in self-passivation by forming compact Al2O3...
