Near-congruent solidification of castings
Chaput Kevin J. Ph.D., Purdue University, May 2015. Near-Congruent Solidification of Castings. Major Professor: Kevin Trumble. A study on the microstructure development of as-cast Cu-Mn alloys based around the congruent minimum at 34.6 wt % Mn and 873 oC was performed. Initially, this was to evaluate the alloy as an alternative to wide freezing range Pb and Sn bronzes that are plagued with poro...
متن کاملUpward and downward unsteady-state directional solidification of a hypoeutectic Al-3wt.%Mg alloy
Solidification thermal parameters, such as growth rate, cooling rate and dendrite arm spacing ( ), have been measured in a hypoeutectic Al-Mg alloy directionally solidified under upward and downward transient heat flow conditions. The experimental setup used in this work consists of a water-cooled mould with heat being extracted from the bottom or the top, promoting upward and downward directio...
متن کاملExistence for a stationary model of binary alloy solidification
— A proof of existence is given for a stationary model of alloy solidification. The System is composed ofheat équation, soluté équation and Navier-Stokes équations. In the latter, Carman-Kozeny penalization of porous medium models the mushy zone. The problem is first regularized and a séquence of regularized solutions is built thanks to Leray-Schauder's fixed point Theorem. A solution is then e...
متن کاملStudy on Solidification Behavior of Aluminium alloy (LM6) Castings by using Computer aided Simulation software
Method layout of a casting is an important aspect of tooling development. It involves decisions regarding part orientation in mould, parting line, cores, cavity layout, feeders, neck and gating system. An improper method layout leads either poor quality or low yield, which affects the productivity. Method design is mostly carried out manually, using 2D drawing of the cast part. Then tooling is ...
متن کاملSolidification Fronts and Solute Trapping in a Binary Alloy
A phase field model with order parameter, concentration, and temperature as field variables is used to study the properties of solidification fronts in a binary alloy. As in previous papers, the model includes dependence of the free energy density not only on these field variables, but also on the gradients of the order parameter and concentration. Terms with these gradients represent surface f...
