  1. 16. Topics on Generative Models in Machine Learning

    Författare :Carl Ringqvist; Henrik Hult; Thomas Schön; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Latent variable models have been extensively studied within the field of machine learning in recent years. Especially in combination with neural networks and training through back propagation, they have proven successful for a variety of tasks; notably sample gener- ation, clustering, disentanglement and interpolation.

  3. 17. An Experimental Study to Understand the Localized Corrosion and Environment-Assisted Cracking Behavior of AISI 420-Martensitic Stainless Steel

    Författare :Krishnan Hariramabadran Anantha; Jinshan Pan; Robert Akid; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Sammanfattning : Motivation and aim: Currently steel molds are designed with cooling channels to reduce the solidification time of molten plastic within the mold to improve the productivity. As water is generally used as the cooling medium, corrosion and environment-assisted cracking (EAC) leading towards the dysfunction of mold, can increase the production downtime. LÄS MER

  4. 18. High Resolution Microanalysis of Creep Resistant 9-12% Chromium Steels

    Författare :Lars Lundin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; martensitic stainless steel; TEM; modified 12% chromium steel; creep resistant; atom-probe field-ion microscopy;

    Sammanfattning : This thesis deals with detailed studies of the microstructure of 9-12% chromium steels. Three alloys with improved creep resistance have been studied in different stages of heat treatment and after creep testing. Two of them were manufactured using PM/HIP and were of the type 10.

  5. 19. Microstructure and Mechanical Properties of High Chromium Steel Weld Metals

    Författare :Guang-Jun Cai; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The microstructure of three types of Cr steel weld metals, containing 5%, 9% and 12% chromium, was studied in different heat treated conditions using optical microscopy, analytical transmission electron microscopy and atom probe field-ion microscopy. The mechanical properties of the weld metals were investigated. LÄS MER
