A turbine engine stator assembly (18) in juxtaposition across a radial gap (26) with a rotary blading assembly (11) includes a radially movable shroud (20) and a gap control member (28) made of at least one shape memory alloy (SMA). The SMA is selected and preconditioned to deform pre-selected amounts to change the radial length of the gap (26) during engine operation responsive to temperature about the SMA. A fluid flow means (30) delivers fluid (34) to the SMA at pre-selected temperatures during engine operation.
