【摘要】:正由英国帝国理工学院研究人员领衔的团队开发了一种基于激光的检测技术,以测量碳化钽和碳化铪这2种陶瓷材料所能耐受的温度限制。结果显示,这2种材料的耐高温性能都超出了此前的认识,碳化钽在温度达到3 768℃才开始熔化,而碳化铪更是在3 958℃时才熔化。这2种材料的优异耐高温性能是航天和核工业所需要的,但此前由于没有合适的检测技术,这2种材料的耐高温性能可以达到
[Abstract]:A team led by Imperial College researchers has developed a laser-based testing technique to measure the temperature limits that two ceramic materials tantalum carbide and hafnium carbide can withstand. The high temperature resistance of both materials is beyond previous knowledge. Tantalum carbide does not melt until the temperature reaches 3,768 鈩,
