The Corrosion inhibition of an inhibitor namely Copper complex of 1-(8-hydroxy quinolin-2-yl-methyl) thiourea (Cu-HTF) which controls the corrosion of mild steel immersed in an aqueous solution containing 60 ppm Cl has been investigated through electrochemical and mass loss method. The formulation consisting of 60 ppm of Cl and 50 ppm of Cu-HTF offers good inhibition efficiency of 78 %. Polariz...

The various welding parameters such as welding speed, voltage and gas flow rate were varied on HSLA steel and the effects of these parameters on weld bead geometry such as penetration, width & height have been studied. Mathematical equations have been developed using factorial technique. And the result of various effects are shown in tables. (Numerical Values). INTRODUCTION Wide variety of stee...

Systemic administration of hypoxia-selective (64)Cu-diacetyl-bis(N(4)-methylthiosemicarbazone) ((64)Cu-ATSM) has increased significantly the survival time of hamsters bearing human GW39 colon cancer tumors. Radiotherapy experiments were performed in animals bearing either 7-day-old (0.5-1.0 g) or 15-day-old (1.5-2.0 g) tumors. Studies compared animals treated with a single dose of 0, 4, 6, 7, 8...

This work deals with atmospheric corrosion to assess the degrading effects of air pollutants on ferrous and non-ferrous metals and alloys, which are mostly used as engineering materials. An exposure study was conducted in the Tuticorin port area located on the east coast of South India, in the Gulf of Mannar with Sri Lanka to the southeast. Common engineering materials, namely mild steel, galva...

Within the framework of a systems approach, the design of a high performance stainless steel integrated processing/structure/property/performance relations with mechanistic computational models. Using multicomponent thermodynamic and diffusion software platforms, the models were integrated to design a carburizable, secondary-hardening, martensitic stainless steel for advanced gear and bearing a...

Micro-alloyed High Strength Low Alloy steels (HSLA-steels) are widely used in civil construction, automobile and line pipe applications. They contain small quantities of alloying elements between 0,01 – 0,1 wt%, such as Niobium, Titanium, Vanadium, Aluminium and Nitrogen. These steels rely on thermo-mechanical rolling, a technique that simultaneously provides high strength, excellent toughness ...

According to the different construction forms of PBL shear connectors in steel-concrete composite beam and steel-concrete joint section, eight finite element models in two groups of the two construction forms are conducted to study different mechanical properties of PBL shear connectors. Following conclusions can be drawn from the finite element method calculation results. The load-slip curve, ...
