摘要

Mn-Cu alloys develop a high damping capacity after a heat treatment of aging and subsequent quenching. The damping capacity developed is extremely sensitive to aging time at a given temperature or temperature for a fixed time. The effect of stress applied during the heat treatment of the commercial alloy Incramute is significant. A tensile load precludes the development of high damping capacity for the aging times investigated (up to 50 hours in some cases). A compressive load only increases the time required to achieve the maximum damping capacity. A preliminary study of the effect of stress applied during heat treatment of Incramute indicates that the major disruption to development of high damping capacity occurs during the aging portion of the heat treatment.
