Superalloys (predominantly the wrought nickel-base alloys containing between 10 and 20% Co) consume roughly 40% of the cobalt in the United States [ Development of two rhenium- containing superalloys for single- crystal blade and directionally solidified vane applications in advanced turbine engines Evaluation of mechanical properties of a low-cobalt wrought superalloy.

L Effect of interstitial content on high- temperature fatigue crack propagation and low- cycle fatigue of alloy. Inconel Inconel is a nonstabilized austenitic stainless steel with low carbon content. [46] In age hardening or precipitation strengthening varieties, alloying additions of aluminum and titanium combine with nickel to form the intermetallic compound Ni3(Ti,Al) or gamma prime (γ′).

Low cobalt (3–6% Co) bonded cemented carbides and silicon nitride substrates are the candidate materials for thin diamond coatings. Adhesion of diamond coating to the tool substrate is a challenging problem in view of diamond’s unique properties and lack of compatibility with most tool materials.

Abstract: The notched low cycle fatigue (LCF) behavior of a P/M (Powder Metallurgy) gas turbine disk superalloy (IN) was investigated to determine the role of inclusions, such as oxides, that are intrinsic in the process of making powder superalloys.

NASA Technical Reports Server (NTRS) Halford, G. Testing for the low cycle fatigue and creep fatigue resistance of superalloys containing reduced amounts of cobalt is described. The test matrix employed involves a single high temperature appropriate for each alloy.

The fatigue endurance limit for the MIM F alloy was determined to be MPa using the smooth geometry which compares favorably with the cast F Using the notched geometry, the fatigue endurance limit was about MPa which is slightly lower than typical values of to MPa for cast F, despite the greater ductility of the MIM F These materials are ideal for precision equipment components as their thermal expansivity is as low as that of Si.

Because the thermal expansion property of these alloys is as low as that of Si, they are most suitable for precision equipment parts. Vanadium increases fatigue strength and improves notch sensitivity.

Vanadium increases wear resistance, edge-holding quality, and high-temperature strength. It is therefore used mainly as an additional alloying element in high-speed, hot-forging, and creep-resistant steels. It promotes the weldability of heat-treatable steels.

The mechanical and thermal swelling stress may promote tool fatigue or failure through crack initiation, low cobalt content or a B-SiC binder phase are therefore preferable for turning operations on 5/5(1).

GROOVER Professor of Industrial and Manufacturing Systems Engineering Lehigh University. When a polymer is subjected to a step constant stress, polymeric materials experience a time-dependent increase in strain.

This phenomenon is known as viscoelastic creep. It is temperature dependent and tests are conducted in the same manner as for metals. Creep modulus is a parameter to quantify this behavior of polymeric materials. Enciclopédia dos Materiais. Notas de estudo Engenharia Notas de estudo Engenharia de Materiais.
