The welding of non-heat treatable aluminum alloy AA5052-H34 was performed using pressure-controlled joule heat forge method. dislocation density the work hardened decreases at high temperatures, and it is difficult to suppress affected softening zone during welding. In addition, since alloys have a thermal conductivity, transfer likely occur, control temperature. Therefore, in this study, by op...

This research paper focuses on the laminate composites of carbon steel and aluminium alloy using epoxy resin. For making composite metal laminates, compression molding method is used. Press used for sandwiched plates at 90°C 155 seconds. Izod Charpy Impact test were performed laminated its parent material i.e., Carbon Steel (SAE1042) Aluminium Alloy (6061-T6) to made a comparison with investiga...

Precipitation hardening, because it involves the hardening of the material over a prolonged time, is also called age hardening, or ageing. By the appropriate heat treatment of precipitation hardening, the strength or hardness of some heat-treatable aluminium alloys can be enhanced by the formation of nano-meter sized second-phase precipitated particles within the original phase matrix. The fine...

L The cellular automata (CA) methodology is applied to the case of intergranular corrosion. Appropriate CA rules are generated which can reproduce and predict the advance of a corrosion front. The proposed model shows qualitative and quantitati...

To improve the understanding of the relation between composition, precipitation and the balance of strength and electrical conductivity (as a measure of the stress-corrosion resistance), a number of Al-Zn-Mg-Cu-Zr aluminium alloy plates with different Zn, Mg and Cu contents were produced and studied by Differential Scanning Calorimetry (DSC). It is shown that detailed analysis of the DSC data p...

Intensive melt shearing was achieved using a twin-screw machine to condition an aluminium alloy prior to solidification. The results show that intensive melt shearing has a significant grain-refining effect. In addition, the intensive melt shearing reduces both the volume fraction and the size of porosity. It can reduce the density index from 10.50% to 2.87% and the average size of porosity in ...

INTRODUCTION The aim of the present paper is to compare creep behaviour of aluminium-based alloy (2024AA) prepared by an identical technology with and without reinforcement by short alumina fibres and with two different orientations of fibres. The observed behaviour is analyzed in terms of back stresses obtained by threshold stress approach from steady-state data or by the internal stress appro...
