Abstract Scope |
The use of HIP is of growing interest for AM parts with significant research efforts in place to mature and optimize these systems. Historically HIP has been used to eliminate internal cracks, voids, and pores with subsequent heat treatment performed using conventional technologies to obtain the desired microstructure and mechanical performance. Recently it has been shown in literature and practice that it is possible to integrate HIP and heat treatments in the HIP furnace with the aid of high-pressure gas cooling or quenching, an approach known as High Pressure Heat Treatment(HPHT). One recent development advancing the HPHT technology is steered cooling. Steered cooling enables the HIP system to now cool based on component temperature at a predefined rate for targeting desired material properties. This presentation will cover the most recent HPHT advancements and learnings and review HPHT cast studies performed on AM alloys highlighting both material performance and productivity improvement. |
