Effect of Yttrium Oxide Impurities on the Structure and Properties of Metallic Hafnium
Abstract
The influence of yttrium oxide impurity content of 0 to 0.4 wt.% on the structure and microhardness metal hafniuminvestigated. It is shown that grain size decreases and the Microhardness of hafnium increases monotonically with increasing content of impurities, while increasing Y<sub>2</sub>O<sub>3</sub> content more than 0.3 wt.% is cracking material.Keywords: yttrium oxide, hafnium, microhardness, optical microscopy.
