Izdelava in lastnosti hitrostrjenih trakov Al-Cr = Preparation and characteristics of Al-Cr RST ribbonsŠuštaršič, Borivoj ; Škulj, Irena, 1972- ; Jurči, PeterTopnost Cr v Al je zelo majhna, praktično enaka nič pri sobni temperature in doseže maksimum 0,5 masnih % v bližini tališča. Cr ima od vseh tehnično pomembnih kovin tudi najmanjši difuzijski ... koeficient v Al in sposobnost tvorbe zelo drobnih in stabilnih izločkov. Zato, da bo med umetnim staranjem potekalo izločevalno utrjevanje moramo prej ustvariti ustrezne pogoje. Pripraviti moramo prenasičeno trdno raztopino Al s Cr. To pa je možno le preko tehnologije hitrega strjevanja, saj ustrezno topnost Cr dosežemo le v raztaljenem stanju in jo zadržimo s praktično zamrznitvijo taline. Zato uporabljamo v glavnem dva postopka: atomizacijo z inertnim plinom in nalivanje na hitro vrteči se disk. Izdelane RST trakove ali prah hladno stisnemo in popolnoma zgostimo z ekstruzijo. Sledi še klasična toplotna obdelava zlitine s katero dosežemo želene mehanske lastnosti. V prispevku bomo predstavili značilnosti izdelave hitrostrjenih trakov s postopkom nalivanja na hitrovrteči se valj ter morfološke, mikrostrukturne in mehanske lastnosti te vrste trakov.Source: Program in knjiga povzetkov = Program and book of abstracts (Str. 67)Type of material - conference contributionPublish date - 2007Language - slovenian, englishCOBISS.SI-ID - 644778
