Metal dusting of nickel‐base alloys

Materials and Corrosion, 1996
AbstractMetal dusting, the disintegration of metallic materials into fine metal particles and graphite was studied on nickel, FeNi alloys and commercial Ni‐base alloys in COH2H2O mixtures at temperatures between 450–750°C. At carbon activities ac > 1 all metals can be destroyed into which carbon ingress is possible, high nickel alloys directly by

Hardness and Nickel-Based Alloys

CONFERENCE 2023, 2023
Abstract The issue of hardness testing and nickel base alloys has been a contentious topic in the oil and gas community. In this paper we present the uses of hardness testing with respect to nickel base alloys with examples of limitations and applications.

Diffusion of Hydrogen in Nickel Based Alloys

Journal of Physics: Condensed Matter, 1989
The recovery process of hydrogen dissolved in excess in nickel based alloys is studied by means of the hydrogen quenching method and electrical resistance measurement after isochronal and isothermal annealing treatments. A recovery stage of the electrical resistance due to hydrogen in the alloys shows similar characteristics as observed in resistance ...

Biocompatibility of Nickel-Base Dental Alloys

Biomaterials, Medical Devices, and Artificial Organs, 1974
Four commercial nickel-base alloys were implanted in rabbit muscle for periods of 2 to 54 weeks. Biocompatibility and tissue reaction was assessed by histological and histochemical techniques. Results were compared with control implants of AISI Type 316L stainless steel.

Nickel-base magnetostrictive alloys

Metal Science and Heat Treatment, 1997
Nickel strip 0.2–0.4 mm thick is a traditional magnetostrictive material due to its good adaptability to manufacture and corrosion resistance and an acceptable, though low, biased magnetostriction. However, some of the parameters of commercial nickel that are important for use in magnetostrictive acoustical-electrical transducers are inferior to ...

The metallography of a nickel base casting alloy

Australian Dental Journal, 1975
Abstract— Three groups of tensile test pieces were produced using a nickel base partial denture casting alloy and employing induction fusion in each case. The first group was produced from new metal, the second from metal which had been recast four times, and the third from new overheated metal.

Corrosion of nickel-based dental casting alloys

Dental Materials, 2007
To study the microstructure, corrosion behaviour and cell culture response of two nickel-based dental casting alloys before and after a heat treatment to simulate porcelain firing.The microstructure was studied using scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX).

Nucleation in bulk undercooled nickel-base alloys

Materials Science and Engineering, 1988
The undercooling behaviour of binary Cu1−xNix bulk melts was investigated over the entire concentration range 0 ⩽ × ⩽ 1 using an electromagnetic levitation technique in an ultraclean environment. The elimination of container-wall induced nucleation has led to undercooling levels of bulk melts up to 30 K larger than the highest values obtained so far by

Metallographie examination of TD-Nickel base alloys

Metallurgical Transactions A, 1975
Techniques are evaluated for chemical, electrochemical, and thermal etching of thoria dispersed (TD) nickel alloys. An electrochemical etch is described which yielded good results only for large grain sizes of TD-nickel. Two types of thermal etches are assessed for TD-nickel: an oxidation etch and vacuum annealing of a polished specimen to produce an ...
