In this study, the applicability of an Al-Si alloy with 30 wt% added scrap for automobile pistons was evaluated by investigating melt quality, microstructural characteristics, and tensile properties under modified GBF (gas bubbling filtration) process conditions, including increasing rotor rotation speed adjusting air-line supply inclination angle impeller blade. The quality dramatically improved resulting in a very clean melt, D.I. value decreasing 28%, length oxide layer per kilogram 65%,...

The cytotoxic effect of 3‐ O ‐acetyloleanolic acid, an oleanolic acid derivative isolated from the seeds Vigna sinensis K., was investigated in human colon carcinoma HCT‐116 cells. dose‐dependently inhibited viability Apoptosis characterized by detection cell surface annexin V and sub‐G1 apoptotic populations. number immunostained cells with V‐FITC increased after treatment acid. population also increased. Expression TRAIL‐mediated apoptosis signaling‐related death receptor DR5 acid‐treated...
Ni-Cr-Mo-V steel alloys for high-speed railway brake discs were prepared to investigate the effect of alloying element contents on microstructure and mechanical properties. The Cr, Mo, Mn elements incorporated into alloys, which contained low carbon content in range 0.16 wt.% ~ 0.21 provide sufficient hardenability. austenitized at 940<sup>o</sup>C 1 hour quenched, tempered 610<sup>o</sup>C. Microstructural study showed a martensitic with different sized austenite...
Active brazing of zirconia with metallic alloys is a promising method for enhancing the mechanical property zirconia. However, process and has not been studied in detail because limitation selection materials processing conditions. Here, we successfully brazed Ti-3Al-2.5V alloy using amorphous Zr54Ti22Ni16Cu8 active filler alloy. By manipulating temperature from 800 °C to 860 °C, highest strength ~186 MPa was achieved at °C. Reduced brittle (Zr,Ti)2(Ni,Cu) intermetallic phases formation...
Understanding the wear behavior of Cu-based brake pads, which are used in high-speed railway trains and aircraft, is essential for improving their design safety. Therefore, mechanism these pads has been studied extensively. However, most studies have focused on changes composition not effects manufacturing conditions. In this study, we fabricated commercial containing Fe, graphite, Al2O3, SiO2 using spark plasma sintering under different The microstructures mechanical properties were...
Heat accumulation due to repetitive simple laser processing paths during building up a three-dimensional structure is well-known issue that needs be settled reduce the excessively high residual stress and thermal deformation in powder bed fusion (PBF) additive manufacturing process. Because of dependency path on dispersion, it essential analyze heat phenomenon processing. A computational fluid dynamics (CFD) analysis based volume fraction method used optimize for minimizing local heating PBF...
The hot rolling in the process chain of aluminium rolled products present critical element material quality and influence on productivity. desire to increase letter demand modifications rolling, consequential changes microstructure, crystallographic texture, mechanical formability properties must be knowledge consistently considered planning product. Achieving lower thicknesses hot-rolled band would enable fewer passes with cold rolling; consequently, same number will complete temperatures....
The design and development of highly selective ammonium ionophores, which find important applications in the detection ions aqueous systems for clinical environmental analyses, devolves to a large extent upon understanding nature selectivity binding formed between ionophore ion. We report here structural properties complex ion TDB18C6, has been shown previously have high selectivity. results provide basis successful action this ionophore.
