Conclusions 1. An excess phase of the (Ni, Fe)3TiAl type is precipitated in the grain boundaries of the primary crystals of centrifugal castings of the Kh16N36MBTYuR alloy; it is responsible for cracking of the cold worked alloy. 2. Homogenization of the alloy at 1200°C for 3–5 h leads to solution of the excess phase in the austenite, equalization of the mechanical properties through the section of the casting, and removal of the anisotropy. 3. Precipitation-hardening of the alloy by aging under our experimental conditions does not depend on preliminary homogenizing. 4. Cold working substantially increases the effect of precipitation-hardening on the cast alloy. 5. Increasing the austenitizing temperature, which produces a more homogeneous solid solution, reduces the effect of precipitation-hardening of the cold worked alloy.
