Microstructure and Mechanical Properties of Transient Liquid Phase Bonding Ti3sic2 Ceramic to Sus430 Using an Al Interlayer

Jingxiang Zhao Xichao Li Zuoqiang Dai Jing Shi Qiang Cheng

In the present work, Ti3SiC2 ceramic and SUS430 ferritic stainless steel were joined by transient liquid phase (TLP) diffusion bonding using an Al interlayer at 850-1050 ℃ under vacuum. The interfacial product, morphology evolution and mechanical property were systematically investigated. The joint interface between 900 ℃ and 950 ℃ was well bonded, indicating that TLP diffusion bonding is an effective method for joining Ti3SiC2 to SUS430. At the joint area, alloy elements completely reacted with liquid Al in the interface next to the alloy region and the homogenization was achieved. Contrastively, in the ceramic interface region, the chemical reaction between molten Al and Ti3SiC2 matrix was less vigorous due to the unique crystal structure and chemical properties of Ti3SiC2. Three distinct reaction zones were formed at the interface. Zone I, located at the SUS430/Al interface, was composed of some Al86Fe14. Zones II and III, found at the Ti3SiC2/Al interface, consisted of AlFe3+Al5FeSi+Al3Ti and Ti3SiC2+TiCx, respectively. The evolution mechanism of TLP-bonded joints was discussed based on the interface microstructure and reaction phases. In addition, the tensile strength of the joint increased with increasing bonding temperature, and the SUS430/Al (10 μm)/Ti3SiC2 joint bonded at 950°C exhibited better mechanical properties.

The Fracture Research of Hexagonal Duralumin Nut

Advanced materials research (2010)

Bin Xu Bai Yang Lou

The microstructure, fracture surface topography and mode of hexagonal nut cracked in assembling under air pressure were analyzed with optical microscope and scanning electronic microscope, which are made in contrast with that of hexagonal nut cracked in man-made. The research results show that the man-made fracture of nut was of dimple shape and cracked in toughness mode, which accorded with the fracture behavior of 2Al2 duralumin material. The air-pressure fracture of nut was of right shape and cracked in brittle mode. The fracture mechanism is concluded that crack fountain is formed in surface of nut because of scoring during assembling and then the crack expands rapidly, leading to brittle fracture of the nut.

Effect of prior-austenite grain size on the microstructure and mechanical properties of ultrafine-grained dual-phase layer-structured steel produced by hot rolling of intercritical annealed bainite

Journal of Materials Research and Technology (2023)

Junjie Sun Bin Xu Hao Wang Shengwu Guo Zehui Yan

In this study, ultrafine-grained (UFG) ferrite/martensite (F/M) layer-structured (LS) steels were fabricated by hot rolling of intercritical annealed bainite steels with a rolling reduction of 75% to ease the strength-toughness trade-off dilemma, and the effect of prior-austenite grain (PAG) size of the bainitic steels on the microstructure and mechanical properties were systematically studied. The results showed that the layer thickness of martensite and ferrite was not affected by the PAG size, but the spacing of parallel lamellae bands (PLS), which evolved from the packet of bainite, decreased with the decrease of PAG size. The PLS had negligible influence on strength and ductility, but the decrease of the PLS led to the increase of delamination and both room temperature (RT) and cryogenic toughness enhancement. By reducing the PLS to introduce more delamination in this steel, the RT and cryogenic impact energy were increased 5.7 times (301 J) and 21 times (102 J at −196 °C), but without the sacrifice of strength (over 1.5 GPa) and ductility (total elongation of about 14%), compared with the initial bainite steel with the same composition respectively. The significantly improved toughness, especially the cryogenic toughness, was considered to result from the special UFG dual-phase layered structure as strain localization could be restrained and ductile fracture could be promoted by this special microstructure even at −196 °C. The cryogenic toughness improvement with the decrease of the spacing of PLS was confirmed to originate from the ductile crack path increase induced by delamination.

The Study of Electrochemical Property of Organic Coating on Magnesium Alloy

Advanced materials research (2010)

Bai Yang Lou Yao Tang Ke Miao Bin Xu

Magnesium Alloys are of low density, high specific strength and high strength, leading to much application prospect in industry and civilian use. However, the alloys are restrictedly used because of easy corrosion. In this paper, The Organic coatings on Magnesium Alloys are made. The electrochemical properties of organic coatings are researched by scanning electron microscope (SEM), stereoscopic microscope and electric-chemistry Work station. The research results show that the curves of open-circuit current to time and Tafel polarization shuffle more for the Pu and ER/PU coatings than for base alloy. With addition of the coating, the magnesium alloy has much low corrosion current density (icorr) and high polarization resistance (Rp), and then its Anti-corrosion Property is evidently improved.

In this paper, nano-copper/paraffin thermosensitive composite materials were prepared by high-energy ball milling, and pressed into the glass cylindrical tube by hot press molding. The micro-morphology and particle shape and microstructure of composite particles were observed by SEM, FI-IR, etc, the temperature sensibility of thermosensitive composite materials were tested by self-manufactured thermosensitive testing device. It shows that the way by which high-energy ball milling are prepared, the composite particle coated with good results, dense arrangement of particles, copper particles on the paraffin structure does not produce damage. With copper mass ratio increasing, the thermal conductivity of temperature sensitive composite is improved.
