A review on cryogenic treatment of tungsten carbide (WC-Co) tool material
ABSTRACT Cryogenic treatment is a thermal treatment process in which the parts are usually cooled to temperatures below −70 C (< 203 K) to induce metallurgical changes in materials. The treatment has
Effect of Heat Treatment on Microstructures and Mechanical Behaviors of 316L Stainless Steels Synthesized by Selective Laser Melting
In this work, 316L austenite stainless steels were fabricated by the selective laser melting (SLM) technique, and the as-printed samples were then treated by using two various routines, namely the
Improving scratch-resistance and wear-resistance of VN film by deep cryogenic treatment with liquid nitrogen
ABSTRACT Deep cryogenic treatment is an effective method to improve materials’ properties and has shown a considerable industries application prospect. In this work, deep cryogenic treatment with

Additive manufacturing is a process of transforming 3D CAD models into a finished part by adding layers of material. The technology is being used for more than three decades to make prototypes using
Performance Evaluation of Cryogenic Treated and Untreated Carbide Inserts during Machining of AISI 304 Steel
The cutting tool in the machining process plays an important role as it acts on the working material. There are a few methodologies have been persued to improve tool life, for example traditional


Influence of Deep Cryogenic Treatment on Microstructures and Mechanical Properties of an Ultrafine-Grained WC-12Co Cemented Carbide
Effect of deep cryogenic treatment (DCT) on the microstructures and mechanical behavior of ultrafine-grained WC-12Co cemented carbide was investigated by using XRD, SEM, and DSC. The phase
Metallurgical and mechanical characteristics of cryogenically treated tungsten carbide (WC–Co)
This paper aims to present the metallurgical and mechanical characterization of cryogenically treated tungsten carbide (WC–Co) in terms of α-, β-, γ-, and η-phase particles and wear behavior,
Correlation between morphology and magnetic properties of electrochemically produced cobalt powder particles
Cobalt 3D powder particles were successfully prepared by galvano- static electrodeposition. The electrodeposited cobalt powders were charact- erized by X-ray diffraction (XRD) analysis, scanning
Microstructural effects on the wear resistance of wrought and as-cast Co-Cr-Mo-C implant alloys.
The tribological behavior of two cobalt-base alloys-an as-cast high-carbon and a wrought low-carbon Co alloy-that are used as hip implant materials is examined and preliminary results indicate that Co-Cr-Mo/Co- Cr-Mo alloy pairs both possessing an HCP matrix microstructure tend to exhibit outstanding wear properties.
Synthesis of monodisperse cobalt nanocrystals and their assembly into magnetic superlattices (invited)
High temperature, solution phase reduction of cobalt chloride in the presence of stabilizing agents was employed to produce magnetic colloids (ferrofluids) of cobalt nanocrystals. We systematically
