6. On the hot crack formation during solidification of iron-base alloys
Sammanfattning : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. LÄS MER

8. Tailoring of Liquid Phase Sintering and Microstructure of Sintered Steel
Sammanfattning : The present study intends to interpret the effects of alloying elements on microstructure and mechanical properties via liquid phase sintering of iron and steel powders. The tools involved are thermodynamic modelling, tailoring of powder properties and processing, and optimisation of sintering. LÄS MER
9. Provitamin A Carotenoids in Orange-Fleshed Sweet Potato
Sammanfattning : Vitamin A deficiency is a major nutritional disorder in a large number of developing countries. The disorder is mainly caused by an inadequate intake of preformed vitamin A and provitamin A carotenoids from the diet. It is also recognized that vitamin A deficiency and iron deficiency tend to coexist in many population groups. LÄS MER
10. Towards Abatement of Selected Emissions from Metals Manufacturing
Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER
