In order to analyze the possible source of large TiN inclusion for the high strength tire cord steel. The remelting experiment was conducted via vacuum induction furnace in the laboratory and the artificially prepared TiN particles which of size 50-74 μm and 100-180 μm were added during the remelting process. Simultaneously, combined with the dissolution kinetic model of TiN particle to make a brief analysis for the genesis of lagre TiN inclusion detected in the wire rod. The results show that the TiN particle which of size 180 μm dissolved in the liquid steel completely at only a few seconds. The TiN inclusions detected in the remelted specimens are all of regular shape, which mainly formed during the solidification process, rather than the added TiN particle which are not completely dissolved. It is supposed that the large TiN inclusion detected in the wire rod most likely spring from the continuous casting mould fluxes.

High-strength tire cord steel is mainly used in radial ply tires, but the presence of brittle Ti inclusions can cause failure of the wires and jeopardize their performance in production. In order to control the titanium content during steel production, a thermodynamic model for predicting the titanium distribution ratio between CaO–SiO2–Al2O3–MgO–FeO–MnO–TiO2 slags during the ladle furnace (LF) refining process at 1853 K has been established based on the ion–molecule coexistence theory (IMCT), combined with industrial measurements, and the effect of basicity on the titanium distribution ratio was discussed. The results showed that the titanium distribution ratio predicted by the developed IMCT exhibited a dependable agreement with the measurements, and the optical basicity is suggested to reflect the correlation between basicity and the titanium distribution ratio. Furthermore, quantitative titanium distribution ratios of TiO2, CaO·TiO2, MgO·TiO2, FeO·TiO2, and MnO·TiO2 were acquired by the IMCT model, respectively. Calculation results revealed that the structural unit CaO plays a pivotal role in the slags in the de-titanium process.

A series of as-cast lightweight multicomponent alloys Al(86-x)Mg10Zn2 Cu2 Six (x=0, 0.3, 0.6, 0.9, 1.2 at.%) were prepared by a vacuum induction furnace with a steel die. With the addition of Si, the reticular white Al-Cu phase deposited were gradually replaced by the gray eutectic Mg-Si phase, while the compressive strength of the alloys increases first and then decreases slowly. It is particularly noteworthy that the compression plasticity also exhibits this trend. When the Si content is 0.9 at.%, the compressive strength reaches its maximum at 779.11 MPa and the compressive plasticity reaches 20.91%. The effect of the addition of Si on the serration behavior of alloy was also studied; we found that the addition of Si introduces a new MgSi phase, and with the change of Si is significantly affects the morphology of the precipitated phase, which affects the serration behavior of the alloys. The comprehensive mechanical properties of the alloy are optimal at the critical point where the serration behavior disappears.In this work, we have provided a method and a composition for the preparation of a low-cost, high-strength, lightweight medium-entropy alloys.

The Impact

The mechanical properties and decarburization layer depths after heat treatment have been investigated for the experimental steels，which were melted by means of 10Kg vacuum induction furnace in the laboratory . It has been confirmed that additions of silicon and vanadium can improve strength of the steels and, the tensile strength of the steels increases with silicon content from 1.4% up to 2.0%. The reduction of carbon content and the addition of carbide forming elements decrease the decarburization sensitivity of the steels tested. The tensile strengths of the steels with carbon less than 0.5% are between 1016.88 to 1674.64 MPa, and the impact energy between 15.50 to 34.50 J, which are compared with the tensile strength of 1160.89MPa, the impact energy of 19.00 J for 55SiCrV. The steels with optimized compositions, which consists of 0.4~0.5% C, 1.6~2.0% Si, 0.8% Cr, 0.2% V, have a satisfactory property with high strength, high toughness and good anti-decarburization.
