Abstract
Low-frequency internal friction and elastic modulus were studied for cast manganes-copper alloys with Mn-content from 60 to 90%. Transformation peak and relaxation peak (due to twin boundaries) were observed for all the cast alloys in the temperature range from -150 to 300°C. The results are compared with those of homogenized specimens.
