A Mini Review on Applications and Uses of Alloys
Abstract: Alloys are mixed of metal with other metal or non-metal in the same group that are prepared by mixing of the metals in their molten state through physical processes. An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often …

A Broad Review on the Impact of spring back/spring go During Bending Operation
Abstract: AbstractSpring back is the most important element impacting the perfection of sheet metal components because of the spring back properties of sheet metal, designing forming dies is particularly complex. This is a critical issue since spring back is a common forming issue with metal forming process using high-strength steel sheets. Once a stress is released, the material's elastic recovery forces the metal to spring back into shape. There are several …
