exhibited a distinct rate of size reduction, particle size distribution, and fracture surface appearance. The results showed that the degree of pulverization substantially increased with increasing tin...Effect of microstructure on the breakage of tin bronze machining chips during pulverization via jet millingElham Afshari,Mohammad Ghambari,Hasan FarhangiSchool of Metallurgy and Materials Engineering......
with good self-pulverization performance can be obtained. Over high C/O value is not conducive to the aggregation of iron phase. The smelting reduction conditions have little effect on the mineral... of melting temperature and C/O value, the contents of 12CaO·7Al2O3 and 2CaO·Al2O3·SiO2 in calcium aluminate slag decrease, which result in the decrease of alumina leaching rate. With the increase of C......
activity. Moreover, B additive resultes in the formation of the second phase, and makes the alloys easier pulverization, which greatly improves the activity, discharge capacity and high rate...Study on High Rate Discharge Performance and Mechanism of AB5 Type Hydrogen Storage Alloys 于军1,郭靖洪2,杨柯2,刘国忠1,陈德敏2,张建海1 (1.Suppo Battery Co.,Ltd.,Shenyang 110015,China;2.Institute of Metal Research......
of aches and pains in China. The physicochemical characterization of Baizhi particles is greatly influenced by ultrafine pulverization. To study the physicochemical characterization of Baizhi... by high performance liquid chromatography (HPLC). The results show that after ultrafine pulverization, the plant cell walls are broken into pieces and the extraction yield of imperatorin is increased......
Degradation Characters of La-Mg-Ni-Based Metal Hydride Alloys:Corrosion and Pulverization BehaviorsYi-Ming Li,Yang-Huan Zhang,Hui-Ping RenKey Laboratory of Integrated Exploitation of Bayan Obo Multi... and La4MgNi19, were studied. La1.5-Mg0.5Ni7 with(La,Mg)2Ni7 as main phase presents better discharge capacity and cycling stability. The three alloys suffer severe pulverization and corrosion after......
