Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360

has been accumulated in this field‚ largely by trial-and-error methods. Nevertheless‚ the forging industry has been capable of supplying products that are sophisticated and manufactured to very rigid standards from newly developed‚ difficult-to-form alloys. The physical phenomena describing a forging operation are difficult to express with quantitative relationships. The metal flow‚ the friction at the tool/material interface‚ the heat generation and transfer during plastic flow‚ and the relationships

The Truth Behind 9/11 September 11‚ 2001 is a time in U.S. history that everyone will remember‚ it holds a special place in almost every American’s heart‚ as well as the families in other countries who lost a loved one that day. Several groups of people within our own country and abroad believe that knowledge of this attack was held prior to the actual event. The U.S. government made the citizens believe that two airplanes crashed into the Twin Towers in New York City‚ and one airplane into the

pre corrosion on the mechanical properties‚ fatigue life‚ microstructure and weight density of Aluminium alloy 8011. 3.5 % NaCl solution was used to pre corrode the Aluminium alloy 8011 specimens. The specimens were kept in the solution for 100 hours. After the pre corrosion various test were performed to study the effects of pre corrosion on tensile strength and fatigue life. Aluminium alloy 8011 is used in the production of fins of various heat exchangers which are used in the cooling systems of

Co-Cr-Ni-Fe alloy coatings in 3.5%NaCl solution.The black arrows next to the forward and reverse anodic branches indicate the potential scan directions. Negative hysteresis is said to occur when the current density of the reverse scan is less than that of the forward scan whereas positive hysteresis is said to occur when the reverse scan exceeds the forward scan [33‚34]. The negative hysteresis in the reverse scan of the cyclic polarization curve (Fig.5) indicates that the Co-Cr-Ni-Fe alloy is not susceptible
