Diffusion of Hydrogen in Nickel Based Alloys
Journal of Physics: Condensed Matter, 1989The 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, 1974Four 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, 1997Nickel 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, 1975Abstract— 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, 2007To 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, 1988The 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, 1975Techniques 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 ...

1981
The development of nickel base alloys over the past 40 years from the simple nickel chromium matrix to the multi-element, multi-phase system of today is discussed under two main headings. The first deals with the metallurgy of the alloys and covers alloying practice, the phases present, strengthening mechanisms and heat treatment.

Abstract Forging of nickel-base alloys results in geometries that reduce the amount of machining to obtain final component shapes and involves deformation processing to refine the grain structure of components or mill products. This article discusses the heating practice, die materials, and lubricants used in nickel-base alloys forging ...

Transpassive Dissolution of Nickel-Base Alloys
CORROSION 1993, 1993Abstract Nickel-base (Ni-Cr-Mo) alloy corrosion coupons experience transpassive corrosion thinning at rates as high as 44 mpy (1.12 mm/y) in near-neutral chlorine dioxide pulp bleaching environments. It is believed that the molybdenum in the passive films on these 8-16% Mo-containing alloys is not stable in near-neutral media in the ...
