摘要
使用X射线衍射仪测定出不同氢含量的Ti-30Mo合金的Debye特征温度值以及晶格常数的变化,结果表明随着氢含量的增加,Debye特征温度相应地减小而晶格常数增加,证实了氢含量的增加会导致金属原子间键合力的减弱,从而造成金属脆化。
The variations of Debye temperature and lattice parameter of a Ti-30
Mo alloy with different hydrogen contents have been measured by means of X-ray
diffraction. It was found that as the hydrogen content increases, the Debye tempe-
rature decreases, but the lattice parameter of the alloy is increased. The above res-
ults support experimentally the decohesion theory that hydrogen in metals will
weaken the cohesive force between the atoms and make metals brittle.
