Cast aluminum alloys find widespread application in the automotive and aircraft industries on account of their good castability, corrosion resistance, and high strength to weight ratio. Use of quality indices to rank cast aluminum alloys in terms of their quality has been in vogue since 1980s. Quality indices enable design engineers to select appropriate alloy condition by comparing the changes in quality with the changes in processing parameters like aging temperature and aging time. They also enable design engineers to select an appropriate alloy by way of comparing the quality obtainable with different alloy compositions. The present article highlights the effect of hot isostatic pressing (Hipping) on the quality of cast aluminum alloy 354 by using quality indices Q0, Q, and QC put forth in published literature. It has been observed that material in Hipped condition has higher value of these indices as compared to non-Hipped condition. This behavior is consistent across different aging conditions of the alloy. It is concluded that improvement accruing through Hipping of cast aluminum alloy 354 can be satisfactorily rated by using these quality indices.

The results obtained by ISIM Timisoara to the development of the friction stir welding process (FSW) have supported the extension of the researches on some derived processes, including friction stir processing (FSP). The experimental programs (the researches) were developed within complex research projects, aspects regarding the principle of the process, modalities and techniques of application, experiments for specific applications, being approached. The paper presents good results obtained by friction stir processing of cast aluminum alloys and copper alloys. The optimal process conditions, optimal characteristics of the processing tools were defined. The complex characterization of the processed areas was done, the advantages of the process applying being presented, especially for the cast aluminum alloys: EN AW 4047, EN AW 5083 and EN AW 7021. The characteristics of the processed areas are compared with those of the base materials. The results obtained are a solid basis for substantiating of some specific industrial applications, especially in the automotive, aeronautical / aerospace fields.
