Abstract
An investigation was made on the damping properties of sintered SUS304L stainless steels modified by the corrosion treatment. The results were summarized as follows:
(1) The damping capacity of sintered SUS304L stainless steels modified by the intergranular corrosion treatment was approximately two to forty times as large as the value of as-sintered compacts.
(2) The increases of (St-Ss) in the sintered compact using -100 mesh powders were higher than that of -20/+60 mesh powders, where St and Ss are the damping capacities of specimen with and without intergranular corrosion treatments respectively.
(3) The increases of (St-Ss) on the corrosion time using the corrosion reagent of 10%CuSO4-H2SO4 were higher than by using of 65%HNO3.
