Using Acoustic Emission Pulses to Assess the Ductile–Brittle Transition Temperature of Aluminum Matrix Composites at Negative Temperatures
摘要
Abstract
The mechanical properties of aluminum matrix composites at negative temperatures are assessed experimentally by means of the classification of acoustic emission pulses; attention focuses, in particular, on the ductile–brittle transition temperature. This transition does not occur even at –100°C, and so it is possible to use aluminum matrix composites for suspension components operating in the Arctic and Antarctic.
