Abstract:
This project was ordered by Sandvik Materials Technology and was performed by a group of students at Uppsala university. The purpose of the project was to study precipitation behavior and structure stability in six advanced heat resistant alloys. Each sample were subjected to a creep rupture test in 600 or 700°C depending on the alloy type. Two parts of each alloy where examined; one part which had been affected by creep and another part which was unaffected by creep. A literature study was performed first to gain knowledge of the scientific theory utilized in this project, namely creep, preci

Abstract:
The use of stainless steel in construction is steadily growing, with applications designed to exploit its structural properties, durability, appearance and fire resistance. The mechanical behaviour of stainless steel is fundamentally different from that of carbon steel. The stress-strain curve of stainless steel is rounded without a well-defined yield stress and exhibits significant strain hardening at relatively small strains. Nevertheless, design provisions for bolted connections between stainless steel structural members in current international standards are essentially based on the rules

Global warming and air pollution are the major problems facing the world today. Therefore strict environmental legislation on the emission of harmful gases from motor vehicles has forced the automobile industry to search for alternative materials or new materials for exhaust systems. In order to produce cleaner exhaust gases, the exhaust temperature needs to be increased to approximately 900oC. Therefore, exhaust manifolds are exposed repeatedly to hot gases as they are nearest to the engine requiring good oxidation resistance, thermal fatigue properties, cold workability and weldability.

Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. The magnitude of the residual stresses depends on factors such as manufacturing technology, material, part geometry, scanning strategy, process parameters, preheating temperature and density of the component. In the present work, the magnitudes of residual stresses and distortions in austenitic stainless steel 316L components manufactured

Abstract:
Plasma electrolytic Polishing (PeP) is a non-conventional technology for the surface treatment of electrically conductive materials. It is an effective machining technique for cleaning and polishing of metals and considered as a more environmentally friendly alternative to the electropolishing process. The electropolishing process uses aggressive media such as acids, whereas in PeP, acids or toxicants are replaced by low concentrated water solutions of various salts. In PeP, high DC voltage is applied to the electrodes in the aqueous electrolyte solution, which establishes a thin steam-gas lay

Structural integrity assessment of nuclear components assessed using the R6 Failure Assessment Diagram approach requires an understanding of the limiting condition in terms of both fracture and plastic collapse. For ductile materials, such as stainless steels used for nuclear components, including the primary pipe-work of a Pressurised Water Reactor (PWR), the limiting condition defined by plastic collapse is likely to occur prior to the initiation of fracture. This is due to the relatively low yield stress of the material and the high fracture toughness. If this is the case, structural integr

Abstract:
碩士<br>國立中央大學<br>機械工程研究所<br>98<br>Stainless steel is widely used in industry due to its unique properties in strength and cor rosion resistance. Stainless steel treated by salt bath could introduce nitrogen and oxygen atoms to diffuse into matrix forming i ron oxide and chromium oxide and nitride as well to enhance the surface hardness for wear resistance. In the present study, three types of stainless steel, 304, 430 and 17-4 PH stainless steel were prepared and treated in NaNO3 (50 wt%) and KNO3 (50 wt%) salt bath for 0.5~2 hours at 450~650oC. After experiment, we observed and examined the th
