BCC MATERIALS OF TITANIUM, ALUMINUM, VANADIUM, AND IRON, AND PRODUCTS MADE THEREFROMNew beta-style (bcc) titanium alloys are disclosed. The new alloys generally include 2.0-6.0 wt. % Al, 4.0-12.0 wt. % V, and 1.0-5.0 wt. % Fe, the balance being titanium, any optional incidental ...
The bcc structure of α-iron is more loosely packed than that of fcc γ-iron. The largest cavities in the bcc structure are the tetrahedral holes existing between two edge and two central atoms in the structure, which together form a tetrahedron. It is interesting that the fcc structure, al...
The effects of micro-alloying element, vanadium, on a BCC Fe SIGMA3(111)[1-10] symmetric tilt grain boundary strength are studied using Density Functional ... S Kim,SG Kim,M Horstemeyer 被引量: 0发表: 2011年 Solubility of carbon inα-iron under volumetric strain and close to the Σ5...
At 912 °C and below, the crystal structure again becomes the bcc α-iron allotrope.[7]The physical properties of iron at very high pressures and temperatures have also been studied extensively,[8][9] because of their relevance to theories about the cores of the Earth and other planets. ...
Experimental observations show that BCC metals such as iron (Zaretsky, 2009, De Rességuier et al., 2012), tantalum (Zaretsky and Kanel, 2014), and vanadium (Zaretsky and Kanel, 2014) do not display this behaviour, and the dynamic yield point either remains unchanged or decreases slightly ...
(fcc) at 1394 °C, when it is known as γ-iron, or austenite. At 912 °C the crystal structure again becomes bcc as α-iron, or ferrite, is formed, and at 770 °C (the Curie point, Tc) the iron becomes magnetic. As the iron passes through the Curie temperature there is no ...
After nearly two decades development, ReaxFF has been applied successfully in various computational chemistry field: heterogeneous catalysis, vanadium catalysts, atomic layer deposition and high energy reaction systems in nanoscale11,12,13,14. Simulation setup The simulation box is set up as a 100 ...
Most of conventional heat resistant steels hitherto developed for use in boiler and turbine materials contained 9 to 12% chromium as well as one or more of carbon, silicon, manganese, nickel, molybdenum, tungsten, vanadium, niobium, titanium, boron, nitrogen and copper, in amounts of 0.04 to...
the Burgers vector. Dislocations can form 3D networks or 2D loops. Extensively consistent experiments have identified two kinds of dislocation loops, one with < 100 > and the other with 1/2 < 111 > Burgers vector, in body-centred cubic (bcc) iron using transmission electron...
