Study on Mechanical Properties and Fracture Behavior of 93W-4.9Ni-2.1Fe Alloy

High-density tungsten alloy is an alloy with tungsten as the matrix (tungsten content is 85%~99%) and a small amount of Ni, Fe, Co, Cu, Mo, Cr, Mn and other elements added. Its density is as high as 16.5~19.0 g/cm3. It has a series of excellent properties such as high density, high strength, good toughness, good machining performance, good electrical and thermal conductivity, small thermal expan

Preparation of spherical niobium powder by radio frequency plasma

Niobium is the lightest refractory metal (density of 8.57 g/cm3), niobium and niobium alloys have high melting point, high high high temperature strength and specific strength, good room temperature machinability, weldability and corrosion resistance, and non-radioactive, which are preferred thermal protection materials and structural materials for aviation and space engines [1-3]. The traditional

3D Printing of Tantalum Medical Metal Materials

Basic Properties of TantalumTantalum metal is silvery white with a density of 16.654 g/cm3. Its high density is related to relative atomic mass, atomic radius and atomic volume. The relative atomic mass of tantalum atom is about 180.95, the atomic volume is 10.9 cm³/mol, and the atomic radius is 0.146 nm. The relative atomic mass per unit atomic volume is large, so its density is high. Tantal

ADDITIVE MANUFACTURING

The term “additive manufacturing” references technologies that grow three-dimensional objects one superfine layer at a time. Each successive layer bonds to the preceding layer of melted or partially melted material. Objects are digitally defined by computer-aided-design (CAD) software that is used to create .stl files that essentially "slice" the object into ultra-thin layers. This inf
