Point defects in aluminum and aluminum dilute 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...

Effects on Structural Aluminum Alloys

HEDRICK, H. G. (General Dynamics/Fort Worth, Fort Worth, Tex.), C. E. MILLER, J. E. HALKIAS, AND J. F. HILDEBRAND. Selection of a microbiological corrosion system for studying effects on structural aluminum alloys. Appl. Microbiol. 12:197200. 1964.Two laboratory methods, a metal-strip test and a tank test, were evaluated as microbiological corrosion systems for producing corroded test specimens...

Microwave Sintering of Aluminum Alloys

Until 2000 almost all research in the microwave sintering area was confined to non-metallic materials. However, after the first report by Penn State in 1999 on full sintering of steel powders in microwave, now in the last few years there has been increasing interest in applying microwave energy for processing of variety of metallic materials. The present study is an extension of this work and r...

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...
