西安交通大学研究团队开发出一种钽合金，可在高达2400摄氏度下保持强度。该成果上月发表于《自然》杂志，可能应用于航空航天和高超音速飞行器。
研究由孙军教授领导，聚焦钽这种熔点近3000摄氏度的金属。团队利用氧化物弥散强化技术，克服了大多数金属在2000摄氏度以上失效的问题。
根据《自然》论文，该合金在极端高温下仍能承受重载。镍基单晶高温合金等传统材料无法达到此温度阈值。
该合金可能用于核反应堆等场景，论文强调其在超高温下的负载性能。

A Chinese electric vehicle with a sodium-ion battery completed a high-speed test on an icy track in northern China despite a tyre blowout. The demonstration highlighted the technology's performance in sub-zero conditions. Changan's Nevo AO6 model, equipped with a CATL battery, is set to reach the market later this year.
