摘要: Abstract The investigation of thermal, mechanical and magnetic behaviors the Cu-11%Al, Cu-11%Al-3%Ag, Cu-11%Al-10%Mn Cu-11%Al-10%Mn-3%Ag alloys was made using microhardness measurements, differential scanning calorimetry, X-ray diffractometry, electron microscopy, energy dispersion spectroscopy moment change with applied field measurement. results indicated that Mn addition changes phase stability range, values makes undetectable eutectoid reaction in annealed Cu-11%Al Cu-11%Al-3%Ag while presence Ag does not modify transformation sequence neither alloys, but it increases this latter at about 2.7 times decreases rates peritectoid reactions former.
