What is hot isostatic materials ?
Hot Isostatic Pressing (HIP) is a special heat treatment process for metallic or ceramic materials and is an important tool for the preparation of high performance materials. The process technology can be used for powder metallurgy molding or for densification of castings (titanium alloys, high-temperature alloys, aluminum alloys and other loose shrinkage castings) after molding. After the hot isostatic treatment, the wear resistance, corrosion resistance and mechanical properties of the material will be greatly improved, and the fatigue life can be increased by 10~100 times.
Processing characteristics:
High temperature Up to 2000°C
High pressure Up to 200 MPa
Isostatic pressure Using an inert gas as the pressure transfer medium, the same pressure is applied uniformly to the surface of the part from all directions.
Main application material systems:
High temperature alloys, titanium alloys, aluminum alloys, copper alloys, refractory metals, hard alloys, stainless steel, corrosion resistant alloys, ceramics, composite materials, electronic materials, functional materials, etc.
Why use hot isostatic materials?
Greatly improves the mechanical properties of the material, increasing its fatigue life by 10 to 100 times
Any material made of products have a certain service life, can not be used indefinitely, the root cause of material failure there are two, one is the internal structure of the material changes, that is, due to the interference of the external environment to change the composition of the material, the new composition can not reach the appropriate performance, the material then failed; another more common reason is that, due to the material internal residual impurities, small cracks, holes, etc., the formation of a sudden change in performance, we call it a material defect, in the working state of the material, for example, when the material is subjected to high temperature cycles and stress cycles, the location of the sudden change in performance will produce a stress concentration effect, and eventually the point produces fatigue. Another more common reason is that, due to residual impurities, small cracks, holes, etc., the formation of a sudden change in performance, we call it a material defect, in the working condition of the material, for example, when the material is subjected to high temperature cycles and stress cycles, the location of the sudden change in performance will produce a stress concentration effect, and eventually fatigue diffusion at the point, so that the material fracture failure. Any of the current conventional molding methods cannot directly eliminate the residual defects inside the material, and all require subsequent treatment processing.
hot isostatic materials, as a special metal heat treatment process, is currently the most effective heat treatment method for eliminating internal defects in materials, and the material forming method that results in the least amount of internal defects in materials. Therefore, hot isostatic pressing is a routine processing step for important critical parts in various fields worldwide.

QUINTUS Hot Isostatic Pressing
Each QUINTUS® hot isostatic press features a cylindrical high-pressure vessel and yoke frame structure with a high-strength prestressed cold-rolled spring wire winding design. Prestressing allows the pressure vessel wall to retain residual compressive stress even at maximum working pressure to eliminate tensile loads and prevent crack propagation and brittle failure.
