Recently, high-speed steel rolls have been used for hot mill work rolls by increasing their carbon and vanadium contents, and were found suitable as replacement for high chromium white cast iron and high Ni-Cr infinite chill iron rolls [1, 2].However, high-speed steel rolls contain many cost alloy elements, such as tungsten, molybdenum, vanadium, niobium, cobalt, etc., which

Effects of Mn, P, S, Si & V on the Mechanical Properties

Effects of Mn, P, S, Si & V on the Mechanical Properties of Steel . The general symbol of a chemical element is represented by:A Z N. where A is the atomic number indicating the number of protons exist in the nucleus of the atom; N is the atomic mass unit, defined as the ratio of the average mass per atom to 1 / 12 of the atomic mass of carbon-12 in its nuclear and electronic ground state Effects of Totally 48 Alloying Elements in Steel (Full The steel rail steel (u-cu) containing 0.20% ~ 0.50% of Cu has a corrosion resistance period 2-5 times of that of normal carbon steel. When the Cu content exceeds 0.75%, the aging effect can be produced after solid solution treatment and aging. When the content is low, its effect is similar to nickel, but weaker. Effects of alloying element and temperature on the Dec 19, 2012 · Effects of alloying element and temperature on the stacking fault energies of dilute Ni-base superalloys.

Investigation on Microstructures and Mechanical Properties In this paper, the effect of Er addition (0.2, 0.5, 0.65, 0.8, 1.0, and 1.5 wt. %) on the microstructure evolution and tensile properties of as-cast hypereutectic Al-10Si-0.8Fe alloy was investigated. The phases and their morphologies in these alloys were identified by XRD and SEM equipped with EDX with the help of metallographic analysis techniques; the length of the secondary phase (LSP) and

Iron Element Facts - ThoughtCo

Oct 03, 2019 · Iron Discovery . Discovery Date:Ancient Times Name:Iron derives its name from the Anglo-Saxon 'iren'. The element symbol, Fe, was shortened from the Latin word 'ferrum' meaning 'firmness'. History:Ancient Egyptian iron objects have been dated to around 3500 B.C. These objects also contain approximately 8% nickel showing the iron may have originally been part of a meteorite.

Si, Mo, W and Al), it is called ferritic steel. Examples are Fe-Cr alloys containing more than 13% Cr, and low-carbon transformer steel containing about 3% Si. 2 Effect on the Eutectoid Point Austenite and ferrite stabilizers widen the respective phase fields. The effect of alloying elements on the Fe-Fe 3 C phase diagram is strongly reflected The Parts of the Periodic Table - Angelo State UniversityW comes from the German name, wolfram ("wolf dirt," so named because of its presence as an impurity in the mining of tin); in some countries, the element is still called "wolfram" 112 Uub The effect of various ternary additives on the oxidation Twenty-four ternary element additions were made to a binary TiAl alloy (Ti34.5 wt.% Al), and the oxidation behavior was studied. As a result of the oxidation tests in air at 1173 K for 360 ks, ternary elements were classified into three groups according to their effects, namely, (a) detrimental; V, Cr, Mn, Pd, Pt, Cu; (b) neutral; Y, Zr, Hf, Ta, Fe, Co, Ni, Ag, Au, Sn, O; (c) beneficial; Nb
