Research status and prospect of Co-phase strengthening in cemented carbide

Cailiao gongcheng
WC-Co cemented carbide has applied in various fields due to its excellent properties. However， the defects of Co bonding phase in hard alloys， such as low hardness， low wear resistance， and poor high-temperature stability， limit their use.

Effect of different maturation methods on silver banana quality / Efeito de diferentes métodos de maturação sobre a qualidade da banana prata

Diversitas Journal, 2019
The marketable banana fruit is climatic and therefore has a short maturation period, which means shorter shelf life. Properly stored storage becomes of great value so that such transformations do not harm the commercialization of fruit.

On Measurement and Interpretation of Toughness Behaviour of Carbide Tools [PDF]

, 1981
The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the quality as defined and the occurrence of chipping and premature failure in cutting.

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

Advanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...
