Grain growth of metal uranium; Rast zrna kod metalnog urana

Abstract

In order to study the grain growth, uranium samples were deformed by molding up to 50% and then by rolling at 600 deg C for recrystallization. Grains obtained by recrystallization having diameter 10 - 15 {mu} were heated at different temperatures and during different time intervals to record the changes of grain size. Characteristic grain growth values, rate constants, time exponent and activation energy, were calculated by using the obtained data. U cilju proucavanja rasta zrna uzorci urana deformisani su valjanjem do 50%, a zatim zareni na 600 deg C da rekristalisu. Rekristalizacijom su dobijena sitna zrna, precnika 10-15 {mu} koja su zatim podvrgavana zarenju pri raznim temperaturama i razlicitm vremenskim intervalima, pri cemu je pracena promena velicine zrna. Na osnovu dobijenih podataka izracunate su karakteristicne velicine rasta zrna: konstante brzine, vremenski eksponent i energija aktivacije (author)
