Rapid Solidification of Al,Mg and Ti

This paper discusses the advantages of rapidly solidifying the light metals aluminum, magnesium, and titanium and rationalizes the characteristics observed in terms of the alloying behaviors of these systems. The present status of rapidly solidified alloy development for the three base materials is reviewed and some projections are made for possible future developments. Further, basic alloy behavior patterns are considered in terms of the performance improve-ments attainable through rapid solidification technology.     

Applications of Rapid Solidification

The attributes of rapid solidification have been sufficiently developed for both crystalline and amorphous materials that commercial products are now available. The constitutional and microstructural advantages to be gained using rapid solidification have been used to develop improved structural alloys form crystalline materials and enhanced mechanical, chemical, electrical and magnetic properties in amorphous alloys. Some predictions are made on which segments of the array of rapidly solidified materials will prove to be of significant commercial value in the future.     

Modeling mechanical alloying: Advances and challenges

While mechanical alloying is a commercial entity for oxide-dispersion-strengthened superalloys, its application to other systems has run into a number of scientific and commercial barriers. In part, this is due to the inadequate scientific underpinning. This article reviews the status of the modeling of the mechanical alloying processes and suggests an approach to improving current knowledge of the process.
