Determination of the influence of interdendritic

Freckles are presently one of the major defects encountered in advanced casting technology. The current state-of-the-art knowledge about freckles is discussed in an extensive critical literature review, including the main physical characteristics of freckles, the current theory of density inversion leading to channel segregation and the various experiments and mathematical models developed so ECS Transactions, Volume 77, Number 11, July 2017, 2017 Corrosion monitoring was also performed using linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) for X-65 carbon steel in gas at 60 °C for dew points between 1 and 18 °C. Corrosion rates ranged between 0.01 and 0.1 m yr-1 and increased with increasing dew point. Corrosion rates were found to depend IOP Conference Series:Materials Science and Engineering Nov 24, 2020 · A composite material of La 0.6 Sr 0.4 CoO 3--BaCe 0.54 Zr 0.36 Y 0.1 O 2.95 (LSC-BCZY) was prepared by mixing sol-gel derived LSC and BCZY powders in different weight percentage (wt%) ratio of LSC to BCZY (LSC:BCZY). The prepared composite powders were denoted as S1 (30:70), S2 (50:50) and S3 (70:30).

Adding Mg to the steel allows the equi-axed crystallization to be facilitated. In particular, the promotion effect is significant in low-carbon steel containing approximately 0.20.25 mass% Ti which leads to crystallizations of TiN until the end of solidification. ISIJ International Steel Science PortalSteel Science Portal is a website for accessing the latest information about steel-related technology. The site provides a cross-search function for accessing treatises in the field of steel technology, a database of report abstracts from the main steel and steel-related journals, links to the principle journals and steel company technical reports, as well as links to steel-related news and MOURAD KEDDAM - Academia.eduMOURAD KEDDAM studies Heat Treatment, Hardness, and Functionally graded materials.

Phase stability under irradiation - ScienceDirect

Jan 01, 1984 · Irradiation of metals and alloys with neutrons, electrons, heavy ions, or -rays may introduce up to 10 8 J/mol of energy in the form of atomic displacements. This energy, which is in the form of vacancies, self-interstitials, and cores of displacement cascades is then available to produce a range of phase changes and microstructural alterations which are not observed under thermal Quenching and Partitioning Treatment of a Low-carbon Quenching and partitioning (Q&P) treatment was applied to a commercial low-carbon martensitic stainless steel, AISI Type 410 (Fe-12Cr-0.1C). The quench interruption temperature was optimized with Recent Progress in High Strength Low Carbon Steels Then, a series of products were gradually developed, such as the hull structure steel 14MnVTiRE (titanium content:0.070.16%), automobile beam steel 06TiL, 08TiL and 10TiL (titanium content:0

Jan 09, 2009 · Accordingly, for 0.49 to 0.61 T/T M, the time exponent n deduced from D 1 n D 0 > 1n = kt increases from 0.15 to 0.30. The observed high thermal stability is attributed primarily to a Zener pinning mechanism arising from the fine Cr 2 /O 3 dispersions and the solute drag effect as well.
