1. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making
Sammanfattning : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. LÄS MER
2. Three Dimensional Determinations of Inclusions in Ferroalloys and Steel Samples
Sammanfattning : As the requirements on material properties increase, there has been a demand on an additional knowledge on the effect of impurities in the ferroalloyson the steel cleanness. Thus, the number, morphology, size and composition of inclusions in sixdifferent ferroalloys (FeTi, FeNb, FeSi,SiMn, LC and HC FeCr) were investigatedin this study. LÄS MER
3. Study of Non-metallic Inclusion in Alloy 825
Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER
4. Acute Pancreatitis. Biomarkers and radiology assessment
Sammanfattning : Background: Acute pancreatitis (AP) is a common and potentially severe disease. Early identification of severity grade is crucial for the outcome of the patient. For study approaches and comparison of inter-institutional data the AP patients need to be uniformly classified. LÄS MER
5. An Experimental Study of a Liquid Steel Sampling Process
Sammanfattning : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. LÄS MER
