16. Modelling and simulation of powder pressing with consideration of friction
Sammanfattning : Finite element modelling and simulation of the powder pressing process can be used in the rational development of powder metallurgy (PM) components. Many of the nonlinear finite element (FE) codes available today can be used for powder pressing simulations. LÄS MER
17. Varestraint Weldability Testing of Cast Superalloys
Sammanfattning : Precipitation hardened Ni- and Ni-Fe- based superalloys, used in hot structural components for aero engines, are subjected to hot cracking phenomena during manufacturing and specifically in welding. This type of cracking involves metallurgical reactions from the liquid phase in concomitance to weld restraints. LÄS MER
18. The isostatic pressure processing of high Tc superconductors and their properties
Sammanfattning : The high Tc superconductors are highly anisotropic, ceramic materials which makes it difficult to sinter them at atmospheric pressure to full density. High porosity is detrimental to their mechanical and electrical properties, so the use of isostatic pressures was used to give higher density materials with improved properties. LÄS MER
19. Microstructure and mechanical properties of low-temperature hot isostatic pressed Ti-6Al-4V manufactured by electron beam melting
Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
20. Multicomponent diffusional reactions in tool steels : Experiment and Theory
Sammanfattning : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.
