Microstructures and Mechanical Properties of Zirconium

The microstructures and mechanical properties of the C/C–ZrO2 composites were investigated. The results indicate that the ZrO2 modified phase is uniformly distributed in the carbon matrix, the bending strength and modulus of C/C–ZrO2 composites are much higher than unmodified C/C composites due to its particle toughening and fiber toughening.

Wear Resistance of Medium Carbon Steel with Different

In this research, the tribological properties of different microstructures of medium carbon steel produced by either an austempered process or quenched-tempered process are investigated. The as-received samples with annealed microstructure (spherodized) are austempered to obtain a bainite microstructure or quenched-tempered to obtain a tempered martensite microstructure.

Abstract: The 2D C/C composites with different microstructures were fabricated by isothermal-isobaric chemical vapor infiltration (ICVI).The mechanical properties of the 2D C/C composites were investigated by 3-point bending tests. The microstructures of the pyrocarbon matrix were observed by polarized light microscope (PLM), scanning electron microscope (SEM), transmission electron microscope

2019/5/15These properties of a carbon fiber-reinforced polymer depend not only on the degradation of the polymer matrix but also on that of the carbon fibers under elevated temperatures. In this study, influences of elevated temperatures (by 700C for 30 min) in air on the mechanical properties and microstructures of a carbon fiber were investigated experimentally.

Effect of Deformation Temperature on Microstructure

2017/5/31This work addresses the influence of deformation temperature in a range from #x2212;40#xb0;C to 200#xb0;C on the microstructure evolution and mechanical properties of a low-carbon high-manganese austenitic steel. The temperature range was chosen to cope at the time during sheet processing or car crash events. Experimental results show that yield stress and ultimate

Microstructures and Electrochemical Properties of Si

The microstructures and electrochemical properties of rapidly-solidified silicon alloys mixed with various forms of carbon have been investigated. Rapidly-solidified Si 70 Ni 15 Ti 15 (at%) alloy (SNT1515) ribbons were prepared by arc-melting, followed by melt spinning process in vacuum.

2019/11/27The elevated temperature resistance and fire resistance of carbon fiber-reinforced polymer (CFRP) composites are a critical concern for many applications. The mechanical properties of carbon fiber at elevated temperatures play a crucial role on the mechanical property of CFRP. In many cases, carbon fiber may not directly exposed to air due to the coverage of resin matrix or coatings at

The Analysis of the Microstructure and Mechanical

The microstructures containing QF, AF and GB in low carbon microalloyed steels can be obtained mainly by UFC process. The amount of AF in steel B is more than that in steel A. The size and distribution of precipitates (Nb/Ti carbonitrides) in steel B are finer and more dispersed than those of in steel A due to relatively low finish cooling temperature.

Microstructures and mechanical properties of bonding

A filler metal wire, Alloy 625, was cladded on a plate of a low carbon streel, SS400, by gas tungsten arc welding, and the morphology of the weld bead and resulting dilution ratio were investigated under different welding parameter values (the input current, weld speed and wire feed speed). The wire feed speed was found to be most influential in controlling the dilution ratio of the weld bead
