摘要: The crystal structure and morphology of hydride (deuteride) precipitates are investigated on ..cap alpha..-titanium specimens containing 1-3 at.% H or D by transmission electron microscopy. is found to have a face-centered tetragonal (c/a = 1.09) with an ordered arrangement hydrogen, being isomorphous ..gamma..-zirconium hydride. Two types precipitation mode observed the habit planes (0110) near (0225).
