The main objective of the project is to develop the technology of manufacturing the B-pillar of aluminium alloys of the 7xxx group, which will have strength properties similar to the currently used pillars made of boron-manganese steel. The use of lightweight high-strength aluminium alloys in the automotive industry will significantly reduce the mass of vehicles and consequently fuel consumption. Aluminium alloys of the 7xxx series have much higher stamina parameters than the 2xxx and 5xxx series alloys and can only compete with boron-manganese steels in terms of specific strength (density strength). However, due to low deformity at ambient temperature, aluminium alloys of the 7xxx group are of limited use in the automotive industry. At present, very intensive work is being carried out on the deformation of this alloy in the aging state. Unfortunately, it turns out that the improvement in deformability at temperatures of about 230-250 amps;C results in a significant decrease in the strength properties of the product, therefore there is no technology developed worldwide for producing B-pillars from this alloy. The project plans to carry out research on the possibility of producing a B-pillar according to two technologies. The first starting material will be the T6 ageing material, which will be shaped in hot tools (temperature should not exceed 230°C), in the second technology the starting material will be directly after rolling (much cheaper) then: hot to a temperature of more than 500 amps;C, cooled during shaping and aging. An additional result of the project will be knowledge of the selection of conditions for effective structure shaping and mechanical properties of car construction elements from 7xxx alloys in sheet metal shaping processes.
