Vplivi vrste in mase jekel ter ohlajevalnih sredstev na njihove lastnosti po kaljenju = [Influence of steel mass and kind and quenching agents on properties after hardening] : magistrsko deloBožič, Slavko, 1971-Toplotna obdelava kovinskih materialov je zelo pomembna tehnologija, s katero dosežemo spremembo njihovih mehanskih lastnosti. Vse večje zahteve uporabnikov po daljši obratovalni dobi delov orodij ... ali konstrukcijskih elementov zahtevajo razvoj ustreznih materialov in tehnologij. Eksperimentalni postopek združuje sestavine ugotavljanja prekaljivosti po lastni zasnovi, ki vključuje tudi informacije o izbranem hladilnem sredstvu. V nalogi so prikazani rezultati ohlajevalnih intenzivnosti nekaterih doma razvitih olj in polimernih vodnih raztopin. Izvedeni so bili številni preizkusi merjenja temperature in merjenja zaostalih napetosti na vzorcih z različnimi masami jekla za poboljšanje 42CrMo4, ki omogoča določevanje mikrostrukturnih sprememb in s tem tudi napovedovanje mehanskih lastnosti jekla. Z opravljenimi raziskavami potrjujemo tehnološko uporabnost 10-15% polimerne vodne raztopine za načrtovanje kaljenja jekla za poboljšanje 42CrMo4.Type of material - master's thesisPublication and manufacture - Ljubljana : [S.
