In this paper, the microstructure, the room-temperature and high-temperature tensile mechanical properties of monolithic TA15 alloy and TiB whisker-reinforced TA15 titanium matrix composites (TiBw/TA15) fabricated by vacuum hot-pressing sintering were investigated. The microstructure results showed that there were no obvious differences in the microstructure between monolithic TA15 alloy and Ti...

Abstract Achieving full densification of some ceramic materials, such as Y 2 O 3 , without sintering aids by spark plasma (SPS) is a great challenge when plastic deformation contributes limitedly to the yield stress material at an elevated temperature higher than applied pressure. Herein, we demonstrate that particle fracture and rearrangement effective strategy promote during pressure-assisted...

Low-pressure powder injection molding (LPIM) is a cost-effective technology for producing intricate small metal parts at high, medium, and low production volumes in applications which, to date, have involved ceramics or spherical powders. Since the use of irregular powders represents promising way reduce overall costs, this study aims investigate potential manufacturing molded from commercial i...

Abstract WC-Co coatings sprayed by HVOF attracted much attentions, benefiting from the satisfactory wear resistance and high bonding strength to steel substrates. Nevertheless, density of conventional required excessive Co binder, which decreased hardness operation life. Based on this, a strengthened WC-30WB-10Co coating was developed with both improved hardness, using high-qualified thermal co...

production of fe-c alloy powders by mechanical alloying was studied. fe and graphite elemental powdermixtures containing 0.8 and 1.5wt.% graphite were mechanically alloyed using a planetary ball mill. thestructural changes of powder particles during mechanical alloying were studied by x-ray diffractometery,scanning electron microscopy and microhardness measurements. for both compositions, mecha...
