Two alloys with designed compositions Cu-10%Al-8%Mn and Cu-10%Al-8%Mn-4%Ag (in wt.%) were prepared by induction melting of pure metals. Microstructures of the prepared samples were investigated in the as-cast state, after homogenization annealing and after quenching. </span></p><p class="TextMJoM"><span lang="EN-US">The effects of different methods of heat treatment on the microstructure and transformation temperatures of the investigated Cu-10%Al-8%Mn and Cu-10%Al-8%Mn-4%Ag alloys were investigated using SEM-EDS and DSC techniques.</span></p><p class="TextMJoM"><span lang="EN-GB">It was determined that after induction melting microstructure of the both investigated alloys are primarily composed of martensite and a small amount of α-phase precipitates.</span></p><p class="TextMJoM"><span lang="EN-GB">Fully martensitic structure in both investigated alloys was obtained after direct quenching from the 850 </span><span lang="EN-US"> °C</span><span lang="EN-GB"> into the ice water. Based on the DSC cooling curves it was determined that two-step </span><span lang="EN-US">martensite transformation for the both investigated alloys occur in the temperature interval from about 30 to -40 °C.</span></p> ER -
