Fatigue Options In ANSYS® Mechanical
Metal casting is one of the most important production process of metal parts and components. Casting of metals is not an easy business and process, it has lots of parameters to be adjusted or designed to obtain succesful casting operations. One of these parameters is the fluidity. All the other parameters and design of metal casting process must done, by considering the fluidity of cast metal.
Fludity is very important parameter and this needed to be evaluated in very serious approach. Fluidity of liquids are generally defined as the inverse of viscosity. As you know that, the internal shear forces of fluids leads the situation of viscosity to withstand to the fluxing. The desire to flux of a fluid is defined as fluidity.
There are some factors that affect fludity of cas metals;
You may think that, we need to increase the pouring temperature of cast metal to the highest possible point, to increase the fludity. But there also another problems in the casting periods with very high pouring temperatures, these problems are;
But freezing mechanisms of metal alloys and metals are quite different. Metal fluids freeze at constant temperature, which means much more easy manipulation of casting temperature. But in metal alloys, there is no exact freezing temperature. In a temperature range, two phases of fluid and solid occur. So, temperature manipulation of temperature is not easy. The solid phase can interfere the flux of fluid sides.
As you understand above, adjustment of proper temperature for pouring temperature of cast metal is not an easy business to achieve desirable fludity. You need to consider lots of kinds of parameters to specify a pouring temperature.
