Sintering and Consolidation of Ti Powders plus Resulting Microstructures
Ti powder compacts can be sintered using a variety of processes, including pressureless sintering under vacuum or inert gas, as well as pressure-assisted consolidation techniques such as vacuum hot pressing (VHP) and HIP. Of course, the microstructure of the sintered Ti alloy depends on the specific process and the processing parameters employed, as well as […]
Pressureless Sintering of Ti Metal Powder
Pressureless sintering includes inert gas and vacuum sintering, which are both reported to have been used for sintering Ti. However, vacuum is far more commonly used than inert gas sintering for Ti. The first experiments aimed at sintering Ti sponge were performed by Kroll in 1937. During these experiments, Kroll used a low-pressure argon atmosphere […]
CIP-sinter-HIP process
The CIP-sinter-HIP (CHIP) process is a multi-step PM process in which a green body/preform is produced via cold isostatic pressing (CIP), conventionally sintered under vacuum, and then hot isostatically pressed to close the remaining porosity [158]. A schematic of this process is given in Figure 19. The CHIP process has enjoyed significant commercial attention. In fact, […]
Powder Metallurgy of Titanium
Powder Metallurgy of Titanium Powder metallurgy (PM) of titanium is a cost-effective alternative to conventional wrought titanium. We are looking at traditional and emerging technologies, including the production of powder, and the sintering, microstructure, and mechanical properties of PM Ti. The production methods of powder are classified into two categories: (1) powder that is produced […]

Dedicated Cold Isostatic Press
Dedicated Cold Isostatic Press We are able to utilize CIP for pre-pressing elementary or blended powders. CIP can be used in conjunction with PM HIP processes or pre-sintering applications. Hot isostatic pressing (HIP) is a process using simultaneous high pressure and temperature over a set amount of time to improve materials properties. These vessels are […]
Atomized Powders Produced with High-Vacuum Furnaces/Smelters
Atomized Powders Produced with High-Vacuum Furnaces/Smelters The process atomized powders are produced with high-vacuum furnaces/smelters and the application-specific combination of melting and atomization techniques enables production of a wide range of super-clean metal powders, including super-alloys, precious metals, refractory and reactive metal powders. There is a choice in the process between two main atomizer types, […]
Titanium Parts for Aerospace Applications
Titanium Parts for Aerospace Applications Titanium parts are frequently found in products used by the aerospace industry for all types of applications. Most of the titanium formed is utilized exclusively in aircraft engines and frames. Titanium is known for its superior strength and low weight. Titanium parts are used the most often for aerospace, giving companies […]
HIP Cladding & Diffusion Bonding (Welding & Joining)
HIP Cladding & Diffusion Bonding (Welding & Joining) HIP is used in a range of applications to clad, weld and join dissimilar materials. For example, sputtering targets are made by HIP consolidation and diffusion bonding of the required coating material and its substrate. Advantages: HIP creates essentially seamless diffusion bonds of similar and/or dissimilar materials […]
Diffusion Bonding as a Joining Technique
Diffusion Bonding as a Joining Technique Diffusion bonding is typically utilized for ferrous parts which are fairly small in size. Hence, part geometry can be a concern. To avoid this complication, sintering and diffusion bonding can potentially be carried out in the same furnace. Diffusion bonding is the solid state joining of two surfaces under intimate contact […]
