  • Vroče utopno kovanje ojnic iz Al kompozita = Hot forging of an Al MMC connecting rod on an industrial scale
    Kevorkijan, Varužan
    In this work, a production procedure already practised on an industrial scale for the forging of aluminium alloys was applied for the closed-die hot forging of Al MMC Al-6061/▫$Al_2O_3$▫/10p ... (supplier: Duralcan Co., USA). The production line consists mainly of a cutting, a forging, a hot trimming, and a heat treatment area. The effectiveness of the production line wqas demonstrated by producing 1160 samples of connecting rods. The temperature of the forged bars was 500[plus minus]10°C, the upper and lower temperatures of the forging die were about 325°C and 320°C, respectively. The forging operation was applied on the screw press with a capacity of 10 MN in order to achieve higher productivity. The forging trial performed demonstrated on an industrial scale that Al MMC, consisting of equiaxial particulate reinforcement having an average paraticle size of less than 10 [mu]m, can be hot forged under a strain rate of 3 s[sup]-1 without damage to the ceramic phase and the generation of other microstructural failures. Dimensional inspection of the forging confirmed thaat the tolerances specified in DIN 1749 were achieved with absolute certainty.
