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.
