By Chen, Y C Nakata, K Friction stir lap joints of AC4C Al alloy (top sheet) and steel (zinc-coated steel, brushed finish steel, and mirror finish steel) were produced when the friction stir welding tool did not touch the lower steel surface. For zinc coat steel, the strength of joints could reach 97.7 pct of that of steel; for brushed finish steel, the strength was 63.2 pct of that of steel; for mirror finish steel, Al alloy and steel could not be welded. The effect of the surface state of...

By Abe, Hiroshi Watanabe, Yutaka Thermal aging embrittlement of light water reactor (LWR) components made of stainless steel cast has been recognized as a potential degradation issue, and careful attention has been paid to it. Although welds of austenitic stainless steels have gamma-delta duplex micro structure, which is similar to that of the stainless steel cast, examination of the thermal aging characteristics of the stainless steel welds is very limited. In this investigation, two types...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
