Small-angle neutron scattering (SANS) and energy-filtered transmission electron microscopy (EFTEM) were employed to characterise the precipitation behaviour in the high-speed steel HS6-5-2 during tempering. With SANS the evolution of the size distribution of precipitates during isothermal tempering at 590 ◦C was investigated. The SANS results are discussed assuming that three populations of precipitates can be distinguished during tempering at 590 ◦C. The smallest population with
