Claim 9:
10. A gas turbine engine comprising:
a compressor;
a combustor downstream from the compressor; and
a turbine downstream from the combustor, wherein the turbine comprises a plurality of stages, and wherein at least one of the plurality of stages comprises:
a turbine rotor assembly, and
an annular shroud encircling the turbine rotor assembly and concentric with the turbine rotor assembly and a longitudinal axis of the turbine,

wherein the annular shroud comprises a split ring having a single split with a first axial edge and a second axial edge on opposing sides of the split, the split ring being formed from a stainless steel or a superalloy,
wherein a radially inward facing surface of the split ring comprises a multi-slope geometry from a leading edge of the split ring to a trailing edge of the split ring,
wherein the split ring includes a first shiplap portion comprising a recess extending from the first axial edge into the radially inward facing surface of the split ring,
wherein the split ring includes a second shiplap portion comprising a recess extending from the second axial edge into a radially outward facing surface of the split ring, and
wherein the first shiplap portion and the second shiplap portion at least partially overlap each other.
