Laser additive manufacturing, and specifically laser powder bed fusion (PBF-LB) enables the production of complex geometries with optimized features that provide unique to components. One main advantages PBF-LB is its capability produce reticular or lattice-type considerably reduce weight Lattice are widely used optimize components mechanically, but, date, their thermal capabilities have not been studied in depth. Therefore, present work, behavior lattice structures analyzed experimentally...
Industrial application of magnesium alloys is increasing in the last decade due to very high mechanical strength weight ratio they present. Typical applications are aeronautic parts but their use automotive industry also growing. The bigger reduction vehicle is, which can be obtain using these alloys, energy saving will near future. However, formability poor and difficult formed at room temperature. Several works have been presented by different authors on positive influence temperature...
As important light-weight structure material, aluminum alloys have been widely used in automotive and aerospace industries. In the last years, manufacturing of parts with high strength good dimensional accuracy has become main objective industrial applications. Within available alloys, 7xxx series attract interest designers due to yield ultimate tensile they present. However, formability these as-received condition is very poor at room temperature various studies are being carried out...
In this work the formability of a high strength aluminium alloy (AA7075-T6) for stamping an automotive component has been studied. Due to low selected alloy, two different heat assisted forming strategies have analysed. On one hand, W-temper process, where thermal process is carried out prior operation. other hot at same time as forming. The results showed that both technology were able form avoiding any failure material. contrary, processes reduced final mechanical properties material...
Shear cutting is a high-speed forming process where material separation involved. The nature of the leads to high strain rates and temperatures on sheared zone subjected operation. In this work, mechanical behavior in terms flow stress, plastic deformation fracture 2205 Duplex stainless steel sheet determined. Uniaxial tension, uniaxial compression, stack plane tension simple shear tests at different angles with respect rolling direction metal are performed determine anisotropic material....
Aluminum 6XXX alloys show high strength to weight ratios and are thus promising materials for today’s transport industry lightweight construction efforts. When considering both deformation final mechanical properties, ductility is interesting from the conformability point of view. On other hand, resistance necessary in automotive structural parts (which can be obtained through T6 precipitation heat treatment) but leads reduced ductility. In order increase aluminum alloys’ formability, warm...
The use of numerical simulations for tool tryout and process control is becoming increasingly prevalent. In this work, the deep drawing a car inner door panel DC06 mild steel numerically analyzed compared with industrial results. Five batches material were mechanically tribologically. Diverse tribological models developed based on experimental strip tests, where Coefficient Friction (CoF) was obtained as function contact pressure, sliding velocity, amount lubricant. A topography analysis...

The increasing demands for lightweight design in the transport industry have led to an extensive use of materials such as aluminium alloys. forming sheets however presents significant challenges due low formability and increased susceptibility galling. tailored workpieces controlled die roughness surfaces are common strategies improve tribological behaviour, whilst galling is still not well understood. This work aimed at analysing interplay between sheet tool surface on friction performance....
Roll levelling is a forming process used to remove the residual stresses and imperfections of metal strips by means plastic deformations. During fibres are subjected cyclic tension-compression deformations leading achieve flat product. The especially important avoid final geometrical errors when coils cold formed or thick plates cut laser. In last years, due appearance high strength materials such as Ultra High Strength Steels, machine design engineers demanding reliable tool for...
Aluminium alloys are more and important for the automotive industry due to their high strength weight ratio elevated ductility; they used many different parts in automobiles as exterior panels, structural parts, brake housings others. However, formability at room temperature is limited. This inconvenient can be improved by increasing forming of part. That lack has lead this research project dealing with tensile behaviour aluminium sheets, conditions strain rate. The analyzed material been...
In the last few years many efforts have been carried out in order to better understand what real contact between material and tools is. Based on understanding new friction models developed which allowed process designers improve numerical results terms of component viability geometrical accuracy. The define coefficient depending different parameters such as pressure, sliding velocity, strain, tool temperature. Many examples improvements achieved, both at laboratory scale industrial scale,...
The roll forming process is a very interesting for the production of profile shaped parts because its high rate, low investment and efficient use material. However, as in most manufacturing processes, set up machine important quality profiles to be manufactured being traditionally used trial error method time scrap consuming. Within up, one variables defined right gap or distance between upper lower at each station. This can lead to, avoid, appearance geometrical errors such differences...
