硼化钽(TaB)高温高压烧结体硬度的研究
Studies of the hardness for the sintered tantalum boride (TaB)at high temperature and high pressure
摘要
Abstract
Tantalum boride has been sintered under high temperature and high pressure (HTHP) conditions by using a DS6×8 MN cubic press device,and the Vickers hardness of TaB has been measured by using a diamond indentation method.Under the applied load of 29.4 N,our test gave the Vickers hardness of TaB are 7.7±0.4 and 10.5±0.7 GPa,at 4 GPa and the temperatures of 900 and 1100 ℃,respectively.Our result shows that the density becomes better with the increasing temperature under the same pressure.By using the Archimedes method,we calculated the relative density of 13.5 g/cm3 for TaB.关键词
