Abstract
U ovom radu provedena je mikrostrukturna analiza Cu-Al-Mn i Cu-Al-Mn-Ti legure s prisjetljivosti oblika. Ispitivanje se provodilo na uzorcima u lijevanom i kaljenom stanju. Istraživane legure su proizvedene “melt spinning“ postupkom. Nakon lijevanja provedena je toplinska obrada dobivenih traka. Toplinska obrada se sastojala od žarenja na 900 ℃ u trajanju 30 min te hlađenja u vodi. Mikrostrukturna analiza je provedena optičkom mikroskopijom (OM), pretražnom elektronskom mikroskopijom (SEM) te energetsko disperzijskom spektrometrijom (SEM). Temperature faznih transformacija određivane su pomoću diferencijalno pretražne kalorimetrije dok je fazni sastav određen pomoću rendgenske difrakcijske analize (XRD). Utvrđeno je da se mikrostruktura lijevane Cu-Al-Mn legure sastoji od β_1 faze i martenzita β_1^, dok se Cu-Al-Mn-Ti legura u lijevanom stanju sastoji od dvofazne α+β mikrostrukture. Toplinskom obradom postignuta je martenzitna mikrostruktura kod obje istraživane legure. DSC analizom su utvrđene temperature faznih transformacija.
Abstract (english)
In this work the microstructural analysis has been performed on Cu-Al-Mn and Cu-Al-Mn-Ti alloy with shape memory effect. The testing was performed on the samples in casting and quenched state. The investigated alloys were produced by a “melt spinnig“ process. After casting, the heat treatment of the obtained ribbons was performed. Heat treatment consisted of annealing at 900 ℃ for 30 minutes and cooling in water. Microstructural analysis was performed by optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive spectrometry (SEM). Temperatures of phase transformation were determinated by differential scanning calorimetry while the phase composition was determined by X-ray diffraction analysis (XRD). It has been found that the microstructure of as-cast Cu-Al-Mn alloy consists of β_1 phase and martensite β_1^, while Cu-Al-Mn-Ti alloy in as-cast state consists of two phase α+β microstructure. Heat treatment resulted in a martensitic microstructure in both investigated alloys. Phase temperature were determined by DSC analysis.
