    Mechanical and ballistic properties of selected titanium alloys used in modern armor systems: Ti6Al4V is an alpha-beta titanium alloy comprised of 90% Ti, 6% Al, and 4% V. It has a density of g/cm3, a hardness of HB, a yield strength of MPa, tensile strength of MPa, charpy impact at 17 J, and elongation at 14% in 2″. Cemented carbides belong to a class of hard, wear-resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a ductile metal binder (u.

    Thus, plastic deformation is restricted such that yield and tensile strengths, as well as hardness, improve. The high-temperature strength of nickel alloys may be enhanced significantly by the addition of about 3 vol% of thoria (ThO2) as finely dispersed particles; this material is .

Ravi Chandran, Z. Zak Fang. This paper focuses on the problem of local mechanical properties estimation in the real microstructure of WC/Co composite. Finite element analysis (FEA) was applied to modelling of the initial. The industrially-important WC-Co composite materials provide a useful, albeit complicated materials system for understanding the combined influences on hardness and strength properties of the constituent WC particle strengths, the particle sizes, their contiguities, and of Co binder hardness and mean free paths, and in total, the volume fraction of by: Various theories are suggested for the plastic deformation of WC‐Co hard metals: in line with [52–54], the deformation of the material takes place inside the binder phase, while in [43, 44] the presence of a constant WC system is suggested and the carbide network is deformed at the same time with the Co binder.

As mentioned in by: 1. Three samples of three WC–15 wt% Co grades were fractured in three-point bending at °C. The composition, WC grain size, some microstructural and mechanical properties of the three grades are given in Table B and C had been doped with VC to hinder the growth of the WC grains during sintering, which is common practice in the production of submicron WC–Co by: 7.

The experimental dependences of strength, plastic properties, hardness, and fracture toughness on sintering or pressing temperature for ultrafine alloy WC wt.% Co are presented. The alloy densifies in solid phase and temperature varies from to °C. The dependences of mechanical properties are extreme, excepting fracture toughness.

The properties reach their Cited by: 1. Ultrafine WC-Co cemented carbides, combining high hardness and high toughness, are expected to find broad applications. In this study, WCCoVCCr{sub 3}C{sub 2} (wt.%) nanocomposite powders, whose average grain size was about 30 nm, were fabricated by spray pyrolysis-continuous reduction and carbonization technology.

However, microstructure is not the only factor affecting the properties of liquid phase sintered materials (1,2). Table lists the specific factors by categories of powder characteristics, sintering cycle, alloy composition, post-sintering heat treatment, sintered microstructure, and testing by: 1.

Co) alloys was examined. The WC-Co is one of the most common hardmetals. It is a liquid-phase sintered powder metallurgical that consists of very refractory carbides embedded in a tough metal binder3.

Hardmetal WC-Co is widely used in oil and metallurgic industries, in particular, in exten. In this study, NiCrBSi wt.% TiN composite (NTC) coating was produced on carbon steel via plasma spraying, with NiCrBSi wt.% WC composite (NWC) coating as the comparison object.

Elastic-plastic deformation took place in the sample. After removing the force, the effect of elastic spring-back occurs – the angle of the part is increased by a value that depends on many parameters.

The usage of an elastic element in the stamp allows us to change the angle of spring-back. The application of beam technologies to produce new materials and components, other than microelectronics, is not a new development.

The influence of the hard-alloy substrate and the composite coatings of a tool on its wear resistance in the machining of high-temperature chromium alloys is investigated.

The effectiveness of the coated hardalloy tool is determined by the properties of the hard alloy and the coatings. For hard alloys characterized by relatively low strength and crack resistance, the coatings prove ineffective.Composite Materials. R.
