Development of high strength aluminum alloy tube for front forks of motorcycles.

Cast Aluminum Alloy for High Temperature Applications

Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Statistical Modeling of Minimum Intergranular Corrosion Path Length in High-Strength Aluminum Alloy

Analytical and Numerical Investigation of Significant Parameters on Strength of Electromagnetically Assembled Aluminum Tube Joints

Electromagnetic forming is a high energy rate forming process in which an electromagnetic Lorentz body force is used for deformation of products.  In this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  The effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...
