Characterizing and Controlling the Metallurgical Properties of a Cu-Mn Alloy for Ship Silencing Applications.
Abstract
Electrical resistivity measurements were used to investigate the effect of stress, applied during aging and quenching, on the specific damping capacity (SDC) of Incramute (a 40 Mn - 58 Cu - 2 Al commencial alloy). It was found that (1) stress applied during either aging, or quenching reduces the SDC of the alloy, (2) the martensitic transformation temperature is a linear function of the stress applied during quenching, and (3) stress applied during the aging treatment retards the aging kinetics. The hystersis of the martensite transformation, and the Neel temperature were determined from resistivity-temperature data. A phenomemological model based on SDC, percent of the martensitic transformation, and applied stress was developed to describe and predict the alloy's SDC behavior under various heat treatment schemes and stress conditions.
