Abstract The US Department of Energy is working with fuel vendors to develop accident tolerant fuels (ATF) for the current fleet light water reactors (LWRs). ATF should be more resilient loss coolant scenarios and help extending life operating LWRs. One proposed concepts use iron-chromium-aluminum (FeCrAl) alloys cladding fuel. A concern in using ferritic FeCrAl that this type may result an inc...

The present research investigates the influence of surface roughness imparted by cold finishing processes on localized corrosion resistance stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic 430F, austenitic 303, 304L, and 316L. It was demonstrated that grinding process, executed previously drawn bars, leads to an improvement in according results obtained with e...

Magnetic dust collected from multiple fusion devices (FTU, Alcator C-Mod, COMPASS) that feature different plasma-facing components (PFCs) and toroidal magnetic fields has been analyzed by means of the X-ray diffraction technique aiming to investigate nature origin magnetism. Analysis led conclusion main mechanism ferromagnetic formation is change iron crystalline phase austenitic ferritic durin...

Introduction/purpose: During exploitation tests of gasoline storage tanks, cracks can form in an austenitic-ferrite welded joint, which compromise the entire tank. Methods: In order to obtain a joint satisfactory strength and durability, paper analyzes influence heat input on tensile characteristics joints. current literature practice, additional materials for welding tank elements are selected...

The goal of this project was to develop low-firing thick-film materials systems for the fabrication of piezoresistive sensors on special steels, for the fabrication of instrumented medical devices. To this end, a series of individual thick-film materials and complete systems, based on lead borosilicate glasses, were developed and extensively characterised. These studies allowed us to formulate ...

In order to form model aluminide coatings for studying critical issues related to their high temperature oxidation and corrosion performance, a laboratory chemical vapor deposition (CVD) procedure is being used to more rigorously control the coating process in terms of composition, purity and microstructure. One ferritic (Fe-9Cr1Mo) and one austenitic alloy (304L) were selected as substrate mat...

Aluminide coatings have been studied for many years because of their excellent corrosion resistance in oxidizing, sulfidizing and carburizing environments. One of the factors that inhibits their application is a lack of sufficient data about their potential benefits. In order to address this issue, model coatings are being fabricated using a chemical vapor deposition (CVD process on ferritic (F...
