Electron zone‐refined tungsten and molybdenum single crystals are deformed in tension at room temperature. The slip systems on the cylinder‐shaped tensile specimens are determined using the light as well as the electron microscope. The slip line pattern depends sensitively on the orientation of the stress axis. Single slip on the crystals investigated is not observed. The slip occurs preferentially on planed of type {110}, but usually further slip planes of the 〈111〉 zone are also active. The slip band structure is discussed in terms of elementary slip processes.
