  1. 1. A Mathematical and Experimental Study of Inclusion Behaviour at a Steel-Slag Interface

    Author : Jenny Wikström; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; CSLM experiments; agglomeration; physical properties; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The aim of this thesis work is to increase the knowledge of inclusion behavior at the steel-slag interface by mathematical modeling and in-situ Confocal Scanning Laser Microscope experiments. Mathematical models based on the equation of motion predicting liquid and solid inclusion behavior was first investigated. READ MORE

  2. 2. Additive Manufacturing of Ti-6Al-4V: Relationship between Microstructure, Defects and Mechanical Properties

    Author : Pia Åkerfeldt; Barbara Shollock; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM) is a relatively new technology that is labelled to be innovative, disruptive, near-net shaping, enabling manufacturing of complex and customised products, for limitless number of applications, directly from the CAD model into real physical parts. For titanium alloys in aerospace applications, AM moreover stands for a reduced material cost, but also for large challenges when considering consistency and qualification of material properties and components in serial production.

  3. 3. Applications of pulsed lasers for phase transformation and welding

    Author : Istvan Sarady; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This work deals with the interaction of pulsed laser radiation with solid, metallic materials at moderate and very high power densities. The interaction mechanism depends upon the properties of both the laser and the target material. READ MORE

  4. 4. Theoretical and experimental studies of a single tooth milling process

    Author : Mathias Werner; Cornel Mihai Nicolescu; Lars Nyborg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hobbing; single tooth milling test; TiN; High speed Steel HSS ; wear mechanisms; cutting force; cutting edge preparation; tool surface preparation; FEM cutting model;

    Abstract : The industrial development of metal cutting processes in gear manufacturing aims at continuously increasing productivity, including increased tool reliability. Basically, the parameters that have an influence on the cutting processes should be known and possible to control.Gear manufacturing is highly important for the automotive industry. READ MORE

  5. 5. High Performance Manufacture of Sintered Steel – Critical Aspects of Tooling Performance and Sintered Microstructure
