Several recent developments in powder metallurgy (PM) rhenium have significantly enhanced the uses and usability of rhenium and rhenium alloys. One of the developments was cold isostatic pressing (CIP) to a complex shape with traditional rhenium powder. A molybdenum-rhenium alloy having an excellent low temperature ductility paired with an excellent high temperature strength. The alloy consists, essentially in % by weight, of 42 up to Cited by:

The quantity of rhenium metal powder used to produce a rhenium chamber is reduced by approximately 70% and the subsequent reduction in machining schedule and.
Introduction. Although the content of rhenium (Re) in the earth's crust is very small and is estimated to be approx. 10 − 7 %, it is irreplaceable in many industrial to its unique structure (with a c/a rate of ), Re has an exclusive combination of properties including high melting point ( °C), high modulus, high strength and ductility at elevated temperatures Cited by: 5.
Current and Future Application of Powder Metallurgical Materials in the Automotive Industry - Duration: European Powder Metallurgy Association 4, views A recent developments in rhenium powder metallurgy (PM) is cold isostatic pressing (CIP) to a near-net-shape (NNS) using traditional rhenium powder.
Rhenium metal powder is packed into a flexible mold having a rigid container to maintain the desired shape (Fig. 1), and the can/ mold assembly is immersed in water contained within a CIP vessel.
MTC and Shimoda Iron Work have collaborated in producing Near Net Shape products for the Oil and Gas industry. Near-net shape product solutions based on powder metallurgy.
Recent developments in the production of net shapes by powder metallurgy, rhenium manufacturing techniques have generated significant saving in both time and budget. For instance, the thrusters of different and unique types of aerospace components (rhenium combustion chambers) were manufactured by means of near-shape technique .
This paper describes the development of a method to produce a near-net shape (NNS) powder metallurgy (PM) rhenium combustion chamber of the size N ( This textbook is written primarily for undergraduate and postgraduate students of metallurgical and materials engineering to provide them with an insight into the emerging technology of powder metallurgy as an alternative route to conventional metal processing.
It will also be useful to students of materials science, mechanical engineering and production engineering to understand and 5/5(5). The purity, preferred orientation, microstructure, microhardness, bonding strength, thickness uniformity and thermal stability of rhenium (Re) coatings prepared on graphite wafers by chemical vapor deposition (CVD) and electrodeposition (ED) in molten salts were comparatively studied in this paper.
