In this age of human civilization, there is a need for more efficient, cleaner, and renewable energy as opposed to that provided by nonrenewable sources such coal oil. sense, hydrogen has been proven be better choice. paper, portable graphite crucible metal smelting furnace was used prepare ten multi-element aluminum alloy ingots with different components. The microstructure phase composition t...

Together with the transition metal carbides and borides, the transition metal nitrides belong to a family of materials that features an unusual combination of outstanding properties, among which are exceptional hardness, high melting point, metallic luster with sometimes vivid colors, and simple metallic structures combined with excellent electrical and thermal conductivities. This combination ...

A new analytical (i.e., without computer modeling) method for calculating the dependence of melting temperature T m a single-component crystal on pressure P is proposed. The based delocalization criterion and does not contain fitting constants. baric dependences (P) its derivative T' gold, platinum niobium in range: P=0-1000 GPa were calculated by this method. It was shown that gold agree bette...

In selective laser melting (SLM) metal powder is completely melted using a high-power beam of 200-400 W to form metallic parts which are almost dense and do not require post processing. To reduce the effective Young's modulus fabricated by SLM that human bone, strut structures with interconnected pores mm size usually adopted for bone implants. contrast, or sintering (SLS) under power below abo...

An induction cold crucible melting is one of the most promising technologies for the reuse and decontamination of the radioactively contaminated metallic materials generated during the dismantling of nuclear facilities, because the crucible ensures a long life operation without generating secondary wastes. Fundamental equipment of the Melting and Recycling of Metals by Cold Crucible (MERC) proc...

Layered Manufacturing can be applied to build "smart" parts with sensors, integrated circuits, and actuators placed within the component. Embedded sensors can be used to gain data for validating or improving designs during the prototype stage or to obtain information on the performance and structural integrity of components in service. Techniques for embedding fiber optic sensors in metals, pol...

High-temperature surface tension and viscosities for five bulk metallic glass-forming alloys with widely different glass-forming abilities are measured. The measurements are carried out in a high-vacuum electrostatic levitator using the drop oscillation technique. The surface tension follows proportional mathematical addition of pure components’ surface tension except when some of the constitue...
