Properties of Melt and Thermal Processes during Solidification in Jewellery Casting
Melt Thermal Processes Jewellery
2009/7/29
A survey is made of the significant thermal properties pertaining to liquid and solidifying jewellery alloys,and some properties of the investment are also considered. Values found in the literature, ...
Influence of solidification rate on microstructure of gravity cast AZ91 magnesium alloy
AZ91 magnesium alloy gravity casting ATD microstructure
2011/4/7
Derivative thermal (ATD) and microstructure analyses of gravity cast AZ91 magnesium alloy are presented. The alloy was cast into cold steel and sand moulds with the same dimensions. ATD curves–solidif...
Kinetic model of ductile iron solidification with experimental verification
Modeling Ductile iron Solidification process
2011/4/1
A solidification model for ductile iron, including Weibull formula for nodule count has been presented. From this model, the following can be determined: cooling curves, kinetics of austenite and eute...

2011/4/1
The paper presents the approximated solution of the solidification problem, modelled with the aid of the one-phase Stefan problem with the boundary condition of the second kind, by using the variation...
The analysis of solidification process of ferritic-austenitic cast steel
Innovative foundry materials and technologies Duplex cast steel Solidification Segregation DDTA
2011/3/29
One of the most common defects leading to the rejection of faulty castings made of duplex cast steel is hot cracking. Hot cracking – differently from cold cracking which occur on cooling, when the ma...
