Pitting growth on clad aluminum alloys with potential slope.

Twinned dendrite growth in binary aluminum alloys

The formation of twinned dendrites (feathery grains) in binary Al–Zn, Al–Mg, Al–Cu and Al–Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G 100 K cm , v 1 mm s , and with slight natural convection in the melt. The influence of the solute element nature and content has been found to be of less importance than previously reported since fea...

Copper and Nickel Alloys Clad with Platinum and Its Alloys JOINING TECHNIQUES AND MECHANICAL PROPERTIES

Technical and economic considerations have identified an opportunity for composite materials which combine certain advantageous features of both noble and base metals. During an investigation of some platinum cladding techniques and of the properties of the resulting bimetals, data have been amassed which could have relevance to industrial a s well as to decorative applications. Here the effect...

Nucleation and Growth of Aperiodic Crystals in Aluminum Alloys

Aluminum and Aluminum Alloys Casting Problems

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...
