The Role of Selenium on the Formation of Spheroidal Graphite in Cast Iron
Sulfur, an element that belongs to group 16 (chalcogens) of the periodic table, is an excellent promoter of nucleation substrates
Influence of graphite morphology on the corrosion behaviour of cast irons for automotive industry
Cast irons are widely used in the automotive industry due to its excellent castability, fluidity, machinability and wear resistance. Particularly,
Finite difference modelling for understanding the hydrogen assisted cracking in virtual slow strain rate tensile tests
Different hydrogen-induced cracking patterns have been observed on two construction steels belonging to the same strength grade for mooring offshore
Comparative study of the metallurgical quality of primary and secondary alsi10mnmg aluminium alloys
The use of secondary aluminium is increasingly being promoted in the automotive industry for environmental reasons. The purpose of this
Improvement of the secondary aluminium metallurgical quality by means of an adequate melt treatment
This work has the purpose to demonstrate that if an adequate melt treatment is applied, it is possible to obtain
When is a Cast Iron Eutectic?
The literature often mentions that cast irons that appear eutectic by thermal analysis are hypereutectic if one refers to the
Correction to: 90 years of thermal analysis as a control tool in the melting of cast iron
Since its first literature mention in conjunction with cast iron in 1931 by Esser and Lautenbusch, thermal analysis (TA) has
Weldability Evaluation of Alloy 718 Investment Castings with Different Si Contents and Thermal Stories and Hot Cracking Mechanism in Their Laser Beam Welds
In this work, weldability and hot cracking susceptibility of five alloy 718 investment castings in laser beam welding (LBW) were
Hot Stamping Research Scenarios from the Last Decade
Hot stamping technology has shown a significant scientific yield in the last decade. The research activity in that field has
Die Material Selection Criteria for Aluminum Hot Stamping
The aim of this work is to develop a die material selection criterion for aluminum hot stamping applications. The criterion
Nodule Count, End of Solidification Cooling Rate, and Shrinkage Porosity Correlations in High Silicon Spheroidal Graphite Iron
High-silicon spheroidal graphite (SG) irons present higher changes of density during the solidification process when compared to normal SG irons.
Quantitative Analysis of Solidification of Compacted Graphite Irons – A Modelling Approach
Several X-ray topography studies which have appeared recently in the literature show compacted graphite in cast iron consisting of coarse
Hydrogen Assisted Fracture of 30MnB5 High Strength Steel: A Case Study
When steel components fail in service due to the intervention of hydrogen assisted cracking, discussion of the root cause arises.
Chunky Graphite in Low and High Silicon Spheroidal Graphite Cast Irons–Occurrence, Control and Effect on Mechanical Properties
Thermal analysis is largely used in cast-iron foundry shops as a means to check melt preparation before casting. It has
Study of Graphite Nucleation in High Sulfur Ductile Irons
It is well known that sulfur is an excellent promoter of graphite and plays an important role in its formation.
Determination of Microshrinkage Risk Index in Ductile Cast Iron Production
One recurrent problem in the foundry industry producing ductile iron castings for automotive industry is the presence of defects of
