90 to 95%of thetheoretical density (21.04g/cc). After the sintering operation, the ingots were encapsulated in a metal can in an operation called canning. The metal cans vere evacuated to a very high vacuum and sealed. This process insures that argon will not permeate the ingots during the hot isostatic pressing (HIPing). tlot isostatic pressing
And if you hang out in metallurgy circles (who wouldn't want to?), you can't hear "additive manufacturing" without also hearing about hot isostatic pressing (HIP). That's because the process, which applies high heat and high pressure to densify parts, has shown promise in improving the performance of high-performance additive
the case of conventional vacuum sintering without external pressure, while temperatures around 1750°C-1900°C4,5 were necessary in the case of pressure sintering techniques such as hot pressing or hot isostatic pressing. In case of sintering above 1700°C (left side Fig. 3), to maintain ﬁne microstruc-
sacriﬁcing the high density of Nd-Fe-B sintered magnets is the key to control the grain growth during sintering. Hot isostatic pressing (HIP) is a manufacturing process used to produce fully dense parts through the application of high temperature and high gas pressure simultaneously (Ref 16-18).
During cold isostatic pressing, any desired object (powder-filled elastic moulds) are compacted isostatically (i.e. from all sides) by means of an effective pressure medium. Thus, the compacted material is homogeneous and has a high density. Our HIP/CIP plant types: Hot isostatic press HIP ISOSTAR; Cold isostatic press CIP ISOMAT

The equipment is mainly used for pressure heating sintering process in vacuum or protective atmosphere in universities, research institutes and other gold compounds, inorganic ceramics, nanomaterials, etc. to obtain high-density products, such as high-precision silicon-washed ceramic bearings.
NbAl 3 has been synthesized from elemental powders by reactive sintering (RS) and reactive hot isostatic pressing (RHIP). Both processes involve a self-propagating exothermic reaction between the constituent powders to form an intermetallic compound. The RHIP approach uses simultaneous external pressurization to make a higher density product.
SPS systems offer many advantages over conventional systems using hot press (HP) sinter‐ ing, hot isostatic pressing (HIP) or atmospheric furnaces, including ease of operation and ac‐ curate control of sintering energy as well as high sintering speed, high reproducibility, safety and reliability.
Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The HIP process subjects a component to both elevated temperature and isostatic gas pressure
by such commercial methods as hot isostatic pressing (HIP) and spark plasma sintering (SPS). HIPed silicon nitride has substantially higher strength and ultimate tensile strengths with high levels of damage tolerance. To overcome the economic limitations of HIP and SPS, a process of cold isostatic pressing with a free low temperature and fast
By the middle 1960s, hot isostatic pressing (HIP) arose as a means to form fully dense high performance materials including titanium, superalloys, and tool steels. The sinter-HIP approach followed, in which the initial sintering is performed under vacuum, this is followed by pressurization late in the cycle to seal residual pores, and all steps
Most of our high-density materials are made by powder metallurgical (PM) processing, metallic encapsulation and hot isostatic pressing (HIP) or hot pressing, though we also frequently employ other green body forming and pressureless sintering processing methods.
Vacuum hot-pressing sintering furnace is mainly used for high-temperature sintering and hot pressing in non-metallic materials, carbon-carbon composite materials, ceramic materials, cemented carbide, synthetic diamond and metal powder materials under vacuum or protective atmosphere can also be used Various materials (such as ceramics, alloys
