This paper presents the chemical and phase composition, microstructure, selected properties both at room temperature corresponding to expected operating conditions of three successive generations TiAl-based alloys (Ti-47Al-2W-0.5Si, Ti-45Al-8Nb-0.5(B,C), Ti-45Al-5Nb-2Cr-1Mo-0.5(B,C)-0.2Si) melted in a vacuum induction furnace with high-density isostatic pressed graphite crucibles. The obtained ...

Tea is very important product in many countries due to huge consumption in the world and its valuable contains. The traditional harvesting method needs to be improved due to its effect on yield and quality. Mechanical plucking as a substitution to conventional method is spreading quickly and is necessary to be investigated for proper adoption. One of crucial factor has been noted to be the heig...

Metallurgical remains such as crucible, mould, slag and tuyere are generated in the production of bronze. The analysis particular can be used to identify raw materials, processes environments (temperature condition) employed bronze fabrication . Gwanbuk-ri site Buyeo is known location a royal palace during Baekje period, 6-7th centuries, crucible fragments slags make were excavated there. purpo...

background : falls are important causes of mortality and morbidity in urban areas and put a high burden on societies. we investigated patterns of fall traumas and related factors in a referral trauma hospital in tehran, iran. methods: in this routine-data-based study, all documents of fall cases in hazrate-rasool hospital, tehran, iran, during october 2014-2015 were investigated. information on...

The use of linear graphs in the development a mathematical model metal melting an induction crucible furnace allows to determine temperature and control excess main parts furnace. In addition, if it is necessary optimize thermal mode operation according presented graph conversion method, any part with desired parameters can be obtained.
