Abstract

Constrained shear strain with subsequent annealing was used to fabricate an in situ Al−Nb metal matrix composite with the fraction of an Al₃Nb intermetallic phase of 25 at %. The composite microstructure was studied. The emission efficiency of the Al−Nb composite samples in a glow discharge was determined, along with those of aluminum and niobium as cold cathodes. The difference in the glow current was analyzed by fixed voltages at cathodes made of the studied materials.

受约束的剪切应变法制备原位Al-Nb金属基复合材料及其在辉光放电中的发射效率

摘要

用约束的应变和随后的退火来制造原位的Al-Nb金属基复合材料，其中Al ₃ Nb金属间相的分数为25 at％。研究了复合材料的微观结构。确定了辉光放电中Al-Nb复合样品的发射效率，以及铝和铌作为冷阴极的发射效率。通过由研究材料制成的阴极上的固定电压分析辉光电流的差异。
