In the present work CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and AISI 1009 low carbon steel plates. Laser power, welding speed, and defocusing distance combinations were carefully selected with the objective of producing welded joint with complete penetration, minimum fusion zone size and acceptable welding pro...

Calculations were performed to quantify the damage parameters in the leading candidate structural and plasma facing materials when used in magnetic and inertial confinement fusion systems and when irradiated in fission reactors. The structural materials considered are ferritic steel, austenitic steel, vanadium alloy and SiC/SiC composite. Plasma facing materials included beryllium, tungsten, an...

Several alloys described as stainless steel which resist tarnish and corrosion in the mouth are being used for a variety of dental appliances and instruments. Probably the greatest application of stainless steel is for orthodontic arch wires and bands, while a more limited use is for temporary space maintainers and crown forms. Root-canal files and reamers designed for endodontic operations als...

iron-aluminum alloys are one of the most resistant alloys against sulfidation/oxidation environments with low oxygen partial pressures. the high sensitivity to hydrogen embrittlement is the main reason for decreasing of their room temperature ductility. there is a drop of strength above 600 c and their creep resistance is fairly weak. it is possible to increase ductility up to 15 percents and i...
