Four piston alloys of different chemical compositions were experimentally investigated. Different temperatures and times (480 °C to 515 °C for 1 h to 60h) of the solution heat treatment were investigated. Additionally, the influence of the aging time and temperature (140-200 °C for 1 h to 30 h) on the hardness was studied. The results have shown that it is necessary to find the optimum combinations of the temperature and the time of heat treatment in order to achieve the required performance and economic savingsV članku so predstavljeni rezultati vpliva toplotne obdelave na mikrostrukturo in mehanske lastnosti aluminijevih zlitin za bate. Eksperimentalno so bile preiskane štiri zlitine za bate z različno kemijsko sestavo. Preiskovane so bile pri različnih temperaturah in časih (480-515 °C od 1 h do 60 h) raztopnega žarjenja. Dodatno je bil preučevan vpliv časa in temperature (140-200 °C od 1 h do 30 h) staranja na trdoto. Rezultati so pokazali, da je za zagotavljanje lastnosti in ekonomičnosti potrebno poiskati optimalno kombinacijo temperature in časa toplotne obdelaveTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
