Abstract
U ovom radu analiziran je učinak toplinske obrade na mikrostrukturu i tvrdoću Cu-13Al-2,5Mn-2Ni legure s prisjetljivosti oblika.Ingoti (promjera 8 mm i duljine 15 mm) proizvedeni su procesom taljenja i lijevanja. Taljenje je izvedeno pomoću toplinske energije proizvedene električnim lukom te su ingoti ohlađeni vodom u posebno konstruiranoj bakrenoj anodi, koja je također služila i kao kalup za lijevanje. Uzorci su analizirani u lijevanom te u kaljenom stanju (900 °C /15 min/H2O). Mikrostrukturna analiza je provedena pomoću optičke mikroskopije (OM), pretražne elektronske mikroskopije (SEM) opremljene uređajem za energetsko disperzijsku spektroskopiju (EDS) te pomoću diferencijalne skenirajuće kalorimetrije (DSC). Preliminarna metalografska analiza ispitivanog ingota potvrdila je da se mikrostruktura sastoji od martenzita u lijevanom i kaljenom stanju. Ispitivanje tvrdoće provedeno je metodom po Vickersu. Tvrdoća ingota Cu-Al-Ni-Mn legure s prisjetljivosti oblika iznosila je 260,5 HV10, a nakon toplinske obrade 285,6 HV10. DSC analizom određene su temperature faznih transformacija (As,Af,Ms,Mf).
Abstract (english)
In this work the effect of heat treatment on microstructure and hardness of Cu-13Al-2,5Mn-2Ni shape memory alloy was determined.Ingots (8 mm in diameter and 15 mm in length) were produced by melting and casting process. Melting was performed using the heat produced by electric arc and by a water-cooled, specially constructed copper anode that also served as a casting mould. The samples were analysed in as-cast state and in as-quenched state (900 °C/15 min/H2 O). Microstructural analysis was performed by optical microscopy (OM), scanning electron microscopy (SEM) equipped by device for energy dispersive spectroscopy (EDS) and using differential scanning calorimeter (DSC). Preliminary metallographic analysis of investigated ingot confirmed that microstructure was consisted from martensite in both, as-cast and as-quenched state. A hardness measurement was performed by Vickers method. Hardness of Cu-Al-Ni-Mn shape memory alloy ingot was 260.5 HV10, and after heat treatment 285.6 HV10. By DSC analysis the phase transformation temperatures (As,Af,Ms,Mf) were determined.
