Refractory elements like W are potent solid solution strengtheners, but they are also heavy and costly. They should be used as sparingly as possible. In the present paper, a series of single crystal alloys are prepared with varying amounts of Ta and Ti, but constant overall refractory concentration and γ'-volume fraction. Partitioning behavior of W and other elements after solutionizing and ageing treatment is investigated. Both, Ta and Ti are able to increase the W content in the γ-matrix. This provides an effective strategy to maximize solid solution strengthening potential for a given overall W content of the alloy. The experimentally determined phase characteristics and homogenization behavior are compared with numerical simulation. Good agreement is observed.
