Dinamična trdnost in lomna žilavost jekel za poboljšanje : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoGliha, ŽanDinamična trdnost je ena izmed najpomembnejših lastnosti, ki vpliva na življenjsko dobo strojnega dela; gredi hidravličnega prijemala. Predstavljena je osnovna zgradba prijemal in prikaz ... obravnavanega strojnega dela. V nadaljevanju so predstavljena jekla za poboljšanje, njihova kemijska sestava ter vpliv legirnih elementov na toplotno obdelavo. Predstavljen je potek toplotne obdelave tovrstnih jekel. Za tem sta predstavljena analiza trenutnega materiala ter proces izbire novega materiala za dinamično obremenjen strojni del. Pri znanih trenutnih obremenitvah je glede na izbrane parametre izbran primeren kandidat za primerjavo s trenutnim. V nadaljevanju so bili pripravljeni vzorci obeh materialov za mehanske preizkuse. Nato so bili opravljeni mehanski preizkusi dinamične trdnosti, trdote, udarne in lomne žilavosti ter analiza prelomnih površin. Na podlagi rezultatov smo oblikovali ugotovitve, kateri material naj bi bil primernejši za trenutno aplikacijo. Ugotovili smo, da ima novi material boljše vse merjene mehanske lastnosti in je primeren za testno vgradnjo. Preverili smo tudi ekonomski vidik zamenjave materiala, ki je sorazmeren z izboljšanjem mehanskih lastnosti.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
