| Abstract Scope |
The size and complexity of the Near Net Shape PM HIPed parts needed for critical applications and extreme environments, is growing and require very large HIP furnaces,. Also, these parts are heavy and weigh thousands of pounds .
Scientific and technological problems to be solved in the development of HIP technology are analyzed:
- deformation and shape control caused by the non-uniform temperature field inside the HIP furnace during heating and ramping the pressure;
- physical and chemical adsorption of air and moisture on the surface of the powder particles and difficulties in outgassing large masses of powder;
HIP modeling and special techniques of pre-processing the powders allow to resolve most of these problems, but needs sophisticated data bases for powder materials
The presentation illustrates several examples of the suggested solutions allowing to produce complex shape non-symmetrical parts up to 100" in size. |
