16. On the Volume Changes during the Solidification of Cast Irons and Peritectic Steels
Sammanfattning : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. LÄS MER
17. On the Experimental Determination of Damping of Metals and Calculation of Thermal Stresses in Solidifying Shells
Sammanfattning : This thesis explores experimentally and theoretically two different aspects of the properties and behaviour of metals: their ability to damp noise and their susceptibility to crack when solidifying. The first part concerns intrinsic material damping, and is motivated by increased demands from society for reductions in noise emissions. LÄS MER
18. Modernising ecodesign : ecodesign for innovative solutions
Sammanfattning : The focus of environmental work in manufacturing companies has increasingly shifted from end-of-pipe solutions to the environmental performance of products and services. The product development process is central to creating value for customers. LÄS MER
