Reflection of 0.1 to 2 keV H atoms from Ti, Fe and their ''metal hydrides,'' together with the H sputtered from the latter, have been calculated using the binary collision cascade program MARLOWE. The fraction of particles and energy reflected is found to decrease with increasing hydrogen content of the metal hydride and this decrease is independent of the incident ion energy. It is found that the heavy metal atoms of the metal hydride are responsible for the reflection and that most of the sputtering is produced by the reflected ion as it exits through the surface layer. It is also found that tritium ions sputter H from ''FeH'' much more effectively than H ions sputter T from ''FeT.''
