Solidification Phenomena and Properties of Some Cast Tool Steels

The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...

Computer Simulation of Directional Solidification of Binary Alloy Calculated under Personal Computer Platform

The objective of this paper is to demonstrate the ability of simulating thermal-solute double diffusivities problem, which is usually calculated via mini-supercomputer or supercomputer, by using typical personal computer (PC). The “plume” phenomena due to buoyant force of lighter liquid solute during solidification will be illustrated. The conduction, convection and macrosegregation predicted b...

Special workshop on: High Performance Computer Simulation of Cooperative Phenomena

In a wide variety of physical systems cooperative phenomena resulting from interactions at the atomic or molecular levels give rise to structures on mesoscopic to macroscopic length scales. The problem of calculating the properties of such systems from simulations based on mathematical models is computationally intense because of the range of length scales and length of time that must be includ...

Thermal Simulation of Solidification Process in Continuous Casting

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
