Gentle layout, excessive protection and luxury, and environmental compatibility are the necessities which effect using fabrics in cars. within the aerospace undefined, there's at the present time a robust necessity to considerably lessen improvement time and prices. Rail cars and ships are characterised via super lengthy lifetime and excessive mileages. The success of those various targets depends upon the provision of novel or greater fabrics and similar approaches.

As a basis for the selected geometry of the cast node, a welded joint geometry was adopted. The nominal dimensions of the welded joint, which has been tested and analyzed in earlier work /4,5/, are presented in Figure 2. One additional aspect for the selection of the cast node geometry was to compare, more or less directly, the performance characteristics of the welded and the cast node with approximately the same nominal dimensions. The final dimensions of the cast node are given in Figure 3. The welded node was produced by MIG-welding two extruded members together; 250 x 250 mm.

These advantage clearly show why thixoforming is now gaining importance as an alternative to the conventional forming processes. The aim of the present investigation was the study of the microstructural evolution of a thixoformed AZ91 during heat treatment. 2 Experimental procedures The chemical composition of the AZ91 studied is reported in Table I. The alloy was produced by Hydro-Magnesium (Norway) in the form of billets; these were thixoformed by STAMPAL (Italy) to produce cylindrical bars 200 mm in length and 10 mm in diameter.
