Conception of tooling adapted to thixoforging of high solid fraction hot-crack-sensitive aluminium alloys G. VANEETVELD1, A. RASSILI1, J. C. PIERRET1, J. LECOMTE-BECKERS2 1. Thixo Unit, B56... Received 13 May 2010; accepted 25 June 2010 Abstract: Thixoforging is a type of semi-solid metal processing at high solid fraction (0.7<φs<1), which involves the processing of alloys in the semi......
Magnesium alloys with low-density (1.7 g/cm3), high specific strength, high stiffness and high elastic modulus ratio, are a research focus field in recent years. Early magnesium alloys have been used..., after multiple pass hot rolling, a lot of deformation twins appear in the alloys. As shown in Fig.1(a), two twins intersect each other, and a high density of dislocations is observed within both twins......

mechanical parts with high performance and high precision[1-3]. Warm compaction is a low cost and effective technique to produce green compact with density higher than 7.5 g/cm3. Warm compaction also... based on FLECK model which was appropriate in the high porosity stage. GURSON model was usually used during the low porosity stage[10]. In the transition stage, REDANZ[11-14] developed a linear......
