Correcting tensile test results of ECAE-deformed aluminium

Proposing a Model for Predicting Flow Stress of Aluminium Alloy in Tensile Test

To obtain materials with desired properties, traditional approaches use experiments, while modern approaches use computer simulation. There is no doubt that computer simulation is cheaper and faster than experiments. By using appropriate computer models, simulation results are in the same accuracy with experiments. In this paper we use genetic algorithm to predict the flow stress of aluminum al...

Structural coarsening during annealing of an aluminum plate heavily deformed using ECAE

The microstructure and softening behaviour have been investigated in an aluminum plate heavily deformed by equal channel angular extrusion and subsequently annealed at 170 °C. It is found that at this temperature the microstructure evolves by coarsening with no apparent signs of recrystallization even after 2 h of annealing. Both coarsening and softening are rapid within first 10 minutes of ann...

Substructural Alignment during ECAE Processing of an Al-0.1Mg Aluminium Alloy

An investigation has been carried out into the microstructures developed during the early stages of equal channel angular extrusion (ECAE) in a polycrystalline single-phase Al-0.13Mg alloy, with emphasis on the substructural alignment with respect to the die geometry and the crystallographic slip systems, which is essentially related to the grain refinement and texture development during deform...

Investigations on Tensile Strength of Aluminium and Nickel Coated Aluminum

Electro less deposition is an autocatalytic chemical technique to deposit a coating of metal on a work piece with the presence of a reducing agent. Electro less nickel coating has high advantages in electroplating. In this work the changing structure of nickel deposits on aluminum and its alloys at the early stage of electro less nickel deposition using sodium hypophosphite ion used as reducing...
