and reduces the precipitated kinetics for Ω phase. Key words: aluminum alloy; aging behavior; microstructure; Ce addition; precipitating kinetics microstructure of alloy 1, as shown in Fig.4(b). The densities of the strengthening phases, including Ω and θ′ phases, increased with aging......
. The addition of different trace elements in the alloy causes different compounds to form in the aging process. Modification of the microstructure distribution inside the alloy can affect the mechanical... on generation of microstructure and resulting properties of the alloy, and dynamic stress-strain behavior exhibits an evident dependence on aging temperature which has an influence on the initial......
and ductility can be obtained after solution treated below beta transus temperature. Key words: beta titanium alloy; Ti-B20; aging treatment; tensile properties; microstructure 1 Introduction Metastable beta... titanium alloys so as to improve the homogeneity of microstructure and composition or enhance the cold formability and aging response. Considering the near critical molybdenum equivalent of Ti-B20 alloy......
J. Cent. South Univ. (2021) 28: 1089-1099 DOI: https://doi.org/10.1007/s11771-021-4682-1 Solution and aging behavior of precipitates in laser melting deposited V-5Cr-5Ti alloys CHAI Peng-tao(柴鹏涛)1... and aging treatments have been applied to eliminating the aggregations of the precipitates. The results show that as the solution temperature increases from 800 to 1560 °C, the densities......
has good casting behavior, but the microstructure of the as-cast alloy is coarse. The eutectic Si phase always presents coarsen plate-like structure, and the β-Al5FeSi phase presents coarsen noodle..., WANG Ben-jing, WU He-bao. Combined effects of mechanical vibration and wall thickness on microstructure and mechanical properties of A356 aluminum alloy produced by expendable pattern shell casting......
Effect of aging on microstructure of Mg-Zn-Er alloys DU Wenbo1,LI Shubo1,LI Jianhui1,WANG Zhaohui1 (1.School of Materials Science and Engineering,University of Technology Beijing,Beijing 100124,China) Abstract:The effect of aging on microstructure of Mg-Zn-Er alloys at 473 K was investigated using hardness measurement, scanning elec-tron microscopy (SEM) and transmission electron microscopy......
of 10 ℃/min. The microstructure was observed using a Philips CM-12 TEM and a JEOL 200CX TEM. Composite aging specimens were prepared using a Gattan-600 ion mill. The matrix alloy specimens were thinned... and the introduction of a large amount of interfaces as well as the reactants generated in the interfaces during the course of casting. At the stage of the peak aging, the S′ phase of matrix alloy......
