A middle-density Mo-Ce-Cu impact-induced energy release structural material was prepared by powder metallurgy, with a density exceeding 99%. A systematic investigation was conducted on the microstructure features, mechanical properties, and energy-releasing behaviour of the alloy. The results show that: no intermetallic compound was formed between matrix Mo and active element Ce in the alloy phase composition; the alloy exhibits good plasticity, with a static failure strain of 38% and a dynamic failure strain of 26.8%; under ballistic gun conditions, the alloy demonstrates favorable impact energy-release performance.

摘要

A middle-density Mo-Ce-Cu impact-induced energy release structural material was prepared by powder metallurgy, with a density exceeding 99%. A systematic investigation was conducted on the microstructure features, mechanical properties, and energy-releasing behaviour of the alloy. The results show that: no intermetallic compound was formed between matrix Mo and active element Ce in the alloy phase composition; the alloy exhibits good plasticity, with a static failure strain of 38% and a dynamic failure strain of 26.8%; under ballistic gun conditions, the alloy demonstrates favorable impact energy-release performance.
