Watch video: Quintus Technologies URQ® – Uniform Rapid Quenching
Hot Isostatic Pressing (HIP) is a proven technology for heat treatment, consolidation of powder and removal of porosity from castings. HIP can be applied to metals, ceramics, composites and plastics.
With typical pressures from 400 to 2,070 bar (5,800 to 30,000 psi) and temperatures up to 2,000°C (3,632°F), HIP can achieve 100% of maximum theoretical density and improve the ductility and fatigue resistance of critical, high-performance materials. The components are often of net shape or near net shape configuration.
Common applications for hot isostatic pressing include defect healing of castings, consolidation of powder metal and ceramic parts or diffusion bonding. The technology is expanding into new applications such as very large castings as well as very large HIP clad P/M to solid or P/M to P/M wear components. Other areas are metal injection molded parts and large P/M parts to replace extended-delivery forgings.
Quintus Uniform Rapid Cooling (URC®) and optional Uniform Rapid Quenching (URQ®) furnaces can provide decreased cycle time, higher productivity, and a unique HIP cycle that includes heat treatment. Benefits are reduced energy consumption, reduced costs, improved quality control and the material is ready for following production steps, i.e machining, polishing, etc.
Pore elimination gives dramatic effects of the fatigue life when it comes to stress levels and number of cycles before failure. Up to 10 times improvement can be achieved by HIPing in the right conditions.
By applying the right conditions in the HIP, post-treatment steps like in a stress relief furnace, the total cycle times can be shortened by 50%.
A proven process for additive manufacturing parts
Common applications for hot isostatic pressing include defect healing of AM parts (pore elimination), consolidation of Titanium powder and diffusion bonding of dissimilar metals or alloys. The technology is expanding into new applications for aerospace applications as well as heat treatment.
Improving parts for the aerospace industry
Of all the HIP installations in the world, more than 50% are utilized to consolidate and improve the material properties of Titanium and Superalloys for the aerospace industry. Today HIP is the standard procedure to give longer and predictive life time of fan blades in an aircraft engine.
Regardless of alloy system, or 3D printing method (EBM, SLM, etc.), HIP is the way forward for optimized material properties and cost savings for safe and efficient production with high quality.
Reasons why you should HIP
100% of theoretical density
Improved material properties
More efficient production
HIP is expanding into new applications such as:
Controlled cooling rates up to 3,000°C/min can be achieved by combining possibilities of pressure and temperature control that the URQ can offer:
Benefits compared to conventional heat treatment methods:
New and unique materials can be achieved
Common applications include
Uniform Rapid Quenching of hammerhead – 500 C/min
Due to the high pressure, quenching in a HIP avoids thermal stresses, warping or cracking of your parts, compared with oil and/or water quenching.
