Residual stress in castings
The customers are more and more interested in the residual stress of their components, which includes also the stress in the casting. 
First, the definition is given and the type and origin of the residual stress explained. Than the overview of all potential residual stress testing methods is shown, with their description. The test selecting criteria are discussed and a comparison between the tests is shown. 
It is very interesting for foundry engineering, sales department and quality department as it also inventories applicable standards.
It can help the customers design, engineering and quality department to understand the residual stress and how to measure it.

Testing of Castings
Overview of all potential testing methods, more detailed for iron and steel castings. 
The start-up of the production (process controlled) and the required test objects, type of testing, re-testing and certifying is described in the first chapter. 
The different fields of testing are described with the preferred test methods. This fields are chemistry, microstructure (including carbides and free graphite), mechanical properties, surface and section quality as well as dimensions and surface roughness. The other physical properties and particular requirements concerning weldability, leakage and corrosion resistant are described separately. 
It is a “must have” for foundry engineering, sales department and quality department as well as for the designers and engineering of companies that use castings (inventories applicable standards).

Chunky Graphite in ductile iron
This non-conformity is one of the most troubling one for thick wall ductile iron castings, although it can also appear in medium sized sections. 
The appearance is described to enable a proper identification. After that, the current different theories that are still not matching will be inventoried. 
A complete chapter is spent for describing the root causes (without them, no chunky graphite) and the influences (increase or decrease the appearance and consequences). 
The testing methods and potential actions are specified with some extra important remarks. 
In the additions, the type of rare earths (one of the root causes) and the sources are inventoried, after which the effect of all common (for ductile iron) elements is mentioned. 
It is a must for foundry engineering and quality department, interesting for melting and production department leaders.
The inspection department of customers can use it for the inspection of the delivered casting.

Free Graphite Evaluation in ductile iron
This is quick and easy to use manual for evaluating the free graphite. 
First the free graphite shape is discussed. Standards involved, testing methods, reporting about the test results and deviating shapes are evaluated. The effect of the shape on the properties is also given. 
The size and nodule count are described by their testing methods and reporting as well as the consequences on the material properties. 
It is very easy to use book for inspectors and engineering department. Customer inspectors can use it as a first and correct evaluation.
It is also well suited for first technical foundry related education.  PDF-format / 45 pages / 25,4 Mb

Graphite Flotation in Ductile iron castings
This book explains the initiation and process that leads to the non-conformity of graphite flotation. The appearance will be described in detail and pictures are shown. 
The next chapter will describe the effects on the volume shrinkage, the riser behaviour and the mechanical properties of the ductile iron. 
All influencing factors are detailed: chemistry, section size, pouring temperature, casting shape, metallurgical metal quality (including inoculation) as well as the Mg- and Bi-content. 
In the last chapters, the common testing is mentioned and rules for avoiding this non-conformity are listed. 
It is very interesting for engineering and quality department. It can also be used by the inspection department of the customer.

NDT (Non-Destructive-Testing) testing
Overview of all potential NDT testing methods for iron and steel castings. 
This book describes all the NDT-tests used in the production and evaluation of castings. The common types (VT, PT, MT, RT) are discussed besides the less common as are ECT, AET, RAM, Residual stress and leak testing. 
The evaluation of the test results (levels) is inventoried and the requirements for the operator are mentioned. There is also a chapter about the selection of the best suited testing method depending on the casting and requirements of the customer. 
An inventory of all standards (EN, ASTM and ISO) are completing the book. 
It is very interesting for readers that are non-specialists in NDT-testing, but regularly involved as are engineering, sales department and quality department (inventories applicable standards). 
It is not a “training” for inspectors but an interesting guidance for non-NDT-operators. PDF-format / 236 pages / 26,1 Mb

Porosity in Ductile Iron castings
The first part is describing the metal shrinkage that initiates porosity. The cooling curve is mentioned as a tool for discovering potential porosity and the influence of the mould and casting section are inventoried. The final item is the elaboration of the root cause(s)and the influences. 
The second part will lead you to the solutions. It is investigated if riserless pouring is possible and if not, how to design the proper (cheapest and most efficient) risers. The effect of chills and padding is also discussed. 
The third chapter will show non-conformities concerning porosity in the castings: riser design and activity, feeding length and types of porosity. 
It is an important tool for engineering and quality department for solving porosity problems. It is a book that every engineer should read and use before he start using simulation programs. 
It is also well suited for the technical foundry related education.  PDF-format / 176 pages / 30,2 Mb

Spectrometer Chemistry Analysis testing
The spectrometer is one of the important testing equipment in the foundry. It is amazing how foundries are using it. 
The first part deals with inventorying the type of spectrometers and explaining the functioning and components of the instrument.
The requirements for the test samples are explained in detail. 
The next chapter gives inside on the testing limits and tolerances of the test result. It sets and explains the instruction for its use: standardizing and calibrating and testing. 
The causes for incorrect results or inventoried: incorrect standardizing and or production sample, incorrect testing or testing conditions, problems with Argon and the representatively of the sample with the casting involved.
As a last item, the testing of carbon in the different testing methods (CE-meter, wet chemical) is explained. 
It is easy to use and important book for the testing operators and quality department employees. It is also very interesting for engineering, and melting department as it also inventories the potential problems.
It is interesting literature for customer inspectors to be aware of the capability and potential incorrect testing results.
