To investigate the effect of solidification parameters on the solidification path and microstructure evolution of Ti-45Al-5Nb(at.%) alloy, Bridgman-type direction
A new sintering method, spark plasma sintering (SPS), is described for the sintering of fine-grained BaTiO<sub>3</sub> ceramics. Dense ceramics with fine grain si
The effect of ultrasonic power and treatment time on degassing of Mg-6Zn-1Ca alloy was studied in this paper. The degassing effect was characterized by measurin
Austempering ductile iron (ADI) is an attractive material due to its excellent comprehensive mechanical properties. However, the deficit in elongation and tough
In this present work,Pb was applied in the Mg97Zn1Y2 alloy to improve its microstructure and properties,using conventional casting methods.The microstructure an
A new selection mechanism termed global annealing selection (GAnS) is proposed for the genetic algorithm. It is proved that the GAnS genetic algorithm converges
