Abstract
U radu su istraživana svojstva Cu-8,3%Al-9,4%Mn (mas.%) legure s prisjetljivosti oblika, nakon toplog i hladnog valjanja. Šipka promjera 8 mm iz Cu-Al-Mn legure, proizvedena je postupkom vertikalnog kontinuiranog lijevanja. Nakon lijevanja provedeno je toplo i hladno valjanje. Toplim valjanjem dobivena je traka debljine 1,75 mm, a hladnim valjanjem traka debljine 1,02 mm. Nakon postupka valjanja uslijedila je toplinska obrada. Toplinska obrada se sastojala od žarenja na 900° C, držanja 30 minuta na toj temperaturi te hlađenja u vodi. Karakterizacija mikrostrukture ispitivane Cu-Al-Mn legure provedena je pomoću optičke mikroskopije (OM) i pretražne elektronske mikroskopije (SEM) opremljene uređajem za energetsko disperzijsku spektroskopiju (EDS). Temperature transformacije i fuzijske entalpije određene su diferencijalno skenirajućom kalorimetrijom (DSC). Tvrdoća Cu-Al-Mn legure prije i nakon valjanja i toplinske obrade određena je Vickersovom metodom (HV10).
Abstract (english)
In the paper, the properties of Cu-8.3%Al-9.4%Mn (wt.%) of shape memory alloy were investigated after hot and cold rolling. The 8 mm diameter rod of Cu-Al-Mn alloy was produced by vertical continuous casting. After casting, hot and cold rolling was carried out. Hot rolling produced a strip of 1.75 mm thick and a cold rolling strip of 1.02 mm thick. After the rolling process was followed by heat treatment. Heat treatment consisted of annealing at 900 °C, holding for 30 minutes at that temperature and cooling in water. Characterization of the microstructure of the Cu-Al-Mn alloy was performed by optical microscopy (OM) and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). Temperature transformation and fusion enthalpy were determined by differential scanning calorimetry (DSC). The hardness of Cu-Al-Mn alloys before and after rolling and heat treatment was determined by the Vickers method (HV10).
