Analysis of fatigue and wear behaviour in ultrafine grained connecting rods
Over the last few years there has been an increasing interest in the study and development of processes that make it possible to obtain ultra-fine grained materials. Although there exists a large number of published works ... -
Analysis of tribological properties in disks of AA-5754 and AA-5083 aluminium alloys previously processed by equal channel angular pressing and isothermally forged
In the present study, the wear behaviour of two aluminium alloys (AA‐5754 and AA‐5083) is analysed where these have been previously processed by severe plastic deformation (SPD) with equal channel angular pressing (ECAP). ... -
Design and mechanical properties analysis of AA5083 ultrafine grained cams
This present research work deals with the development of ultrafine grained cams obtained from previously ECAP (Equal Channel Angular Pressing)-processed material and manufactured by isothermal forging. The design and the ... -
Design, optimization, and mechanical property analysis of a submicrometric aluminium alloy connecting rod
Ultrafine grained materials have a great deal of both scientific and technological interest because they allow outstanding properties to be obtained. An improvement in the mechanical strength and in the ductility and a ... -
Design, simulation and manufacturing of a connecting rod from ultra-fine grained material and isothermal forging
In this research work, a study on the mechanical properties of isothermal forging for connecting rods is made from previously ECAP (Equal Channel Angular Pressing)-processed AA1050 and AA5083 aluminium alloys. This severe ... -
Experimental and FEM analysis of wear behaviour in AA5083 ultrafine-grained cams
Severe plastic deformation (SPD) processes have attracted a great deal of both scientific and technological interest over the last few years as a consequence of the improvements that are possible to obtain in the microstructure ... -
Experimental modelling of critical damage obtained in Al-Mg and Al-Mn alloys for both annealed state and previously deformed by ECAP
Assessing the damage produced in plastic deformation processes permits the optimum manner to shape a material that could avoid any cracks from appearing. In this present research work, the absolute critical damage in ... -
Mechanical properties analysis of an Al-Mg alloy connecting rod with submicrometric structure
Over these last few years, there has been a growing interest in developing mechanical components from submicrometric materials due to the significant improvement that these materials present compared to their original ... -
A proposal of a constitutive description for aluminium alloys in both cold and hot working
The most important difficulties when the behaviour of a part that is subjected to external mechanical forces is simulated deal with the determination of both the material thermo-mechanical properties and its boundary ...
