Microstructure and Mechanical Properties of TiAl-based Alloy

Two phases gamma titanium aluminide alloy,Ti-46.5Al-2.5V-1Cr.was investigated to characterizemicrostructures and to define the microstructure/mechanical property relationship.Many kinds ofmicrostructure of gamma and α_2 phases were obtained by heat treatments in the α+γ,α_2+γ and αfields.The effects of microstructure on tensile properties,fracture toughness and J-R resistancecurve at room temperature,were systematically studied.The experimental results showed that themicrostructure had a strong effect on mechanical properties,The duplex microstructure produced byheat treatment at 1250℃×4 h with controlled cooling resulted in the highest ductility of 4.8% tensileelongation,low fracture toughness and crack growth resistance.The fully lamellar microstructureproduced by heat treatment in the α field having large grain sizes resulted in the highest fracturetoughness but the lowest ductility.     

Application of precedent type analysis (PTA) in the construction of Ertan hydro-electric station, China

Precedent type analysis (PTA) emerged in China in the 1980s. It is a principle and method used for rapid analysis and prediction of rock stability in tunnelling projects. In this paper, PTA is formally defined and emphasis is placed on the application of PTA to the assessment of designs for diversion tunnels at the Ertan hydro-electric station. It compares PTA with the conventional analysis of rock mechanics; it also contrasts their applications and conclusions.
