LOW-FREQUENCY INTERNAL FRICTION OF As-CAST MANGANESE-COPPER ALLOYSWEN YITING, XIE CUNYI and CHEN HUI
Institute of Solid State Physics, Academia Sinica, Hefei, China
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.
