Abstract. The size of the parts needed to be HIPed for critical applications, especially in nuclear, is growing and very often the HIP capsules become so large that they take not only the entire diameter of the HIP furnace, but almost all its volume. Often, these parts weigh thousands of pounds, do not have axial symmetry and cannot stand by themselves in the furnace requiring complex shape supporting frames. For such parts additional problems need to be solved in the HIP tooling design and HIP process itself due to: (1) difficulties in maintaining dimensional accuracy, (2) non-uniform temperature field inside the HIP during heating and ramping the pressure, (3) different mechanical properties in HIP capsule elements and (4) HIP capsule movement during deformation inside the supporting frame. HIP modeling allows to approach these problems. Several examples of the solutions allowing HIPing of complex shape non-symmetrical parts up to 70″ in size are analyzed.
