1. On the hot crack formation during solidification of iron-base alloys
Abstract : 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. READ MORE

2. Air gap formation and hot tearing in solidification processing of Al- and Cu-base alloys
Abstract : Shrinkage in a solidifying metal has been studiedexperimentally as well as theoretically. The main focus hasbeen to examine the mechanisms causing an air gap to formbetween a casting and a mould, and hot crack formation to occurin a solidifying metal. READ MORE

3. Mechanical Behaviour of Adhesive Joints in Cartonboard for Packaging
Abstract : A cartonboard package is often sealed and closed with an adhesive – either a hot-melt adhesive (adhesives that are applied in a molten state on the cartonboard) or a dispersion adhesive (adhesives that are applied as water-based dispersions). This thesis focuses on the process of hot-melt gluing, and how material properties and process conditions affect the performance of the adhesive joint. READ MORE

4. Problems in the Aluminium DC Casting Process Associated with Melt Treatment Operations
Abstract : The quality of DC cast Al alloys is highly dependent on melt batch composition and impurity level in the molten alloy. The chemical composition and cleanliness of a melt is controlled through the melt treatment operations, carried out while the melt is still in the furnace before casting starts. READ MORE

5. Fracture Behaviour of adhesive Joints in carton board
Abstract : A carton-board package is often sealed and closed with an adhesive. Package requirements vary depending on how the package is to be used. A package that is only supposed to protect the product during transport differs from one that is supposed to attract consumers and facilitate the use of the product by consumers. READ MORE
