Process influences on mechanical strength of chemical strengthened glass

Investigation of Mechanical Features at Macroscopic Scale for Friction Stir Welding of Polypropylene Strengthened with 40% Glass Fiber

In this paper experimentally, the friction-stir welding of the polypropylene sheets with 40% glass fiber has been investigated. Comparison to other welding methods, the strength of the joint is the most important feature in this process. Many parameters such as tool geometry, rotational speed, linear velocity, and tilt angle are very important as input parameters in this type of welding. Theref...

Damascene Process and Chemical Mechanical Planarization )e

The constant demand to scale down transistors and improve device performance has led to material as well as process changes in the formation of IC interconnect. Traditionally, aluminum has been used to form the IC interconnects. The process involved subtractive etching of blanket aluminum as defined by the patterned photo resist. However, the scaling and performance demands have led to transiti...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
