Recycling of Al chips and Al chips composites using high-pressure torsion

Pilot in-Situ Production of AL-TiB2 and AL-ZrB2 Composites Using Reactive Slag

In this research work, the possibility of semi industrial production of Al-TiB2 and Al-ZrB2 composites, using reactive slag in a flame furnace have been investigated. For this purpose, commercial pure aluminum and powder mixture of TiO2 (ZrO2) , KBF4 and Na3AlF6 were used. The results showed that using a proper ratio of slag forming materials as well as proper amounts of the above-mentioned com...

Al - Mg - Cu based alloys and pure Al processed by high pressure torsion : the influence of alloying additions on strengthening

The influence of alloying additions on strengthening of high pressure torsion (HPT) processed alloys was investigated using commercially pure Al (Al-1050 alloy) and five Al-(1-3)Mg-(0-4)Cu alloys (in wt%). Microhardness was measured on cross sections. For Al-1050 the microhardness reaches a peak at an effective strain of about 3 and subsequently decreases. The microhardness of Al-Mg-Cu alloys i...

RECYCLING OF AlMgSi1 ALUMINIUM CHIPS BY COLD COMPRESSION

Current work elaborates possibilities for direct conversion of AlMgSi1 aluminium chips into solid billets by solid state recycling. Milling chips from an aluminium alloy were cold compressed in a closed cylindrical die by means of a 2,5 MN hydraulic press. Due to low initial relative density of the chips, several pre-compressions were needed. In order to establish the infl uence of chip geometr...
