  1. 1. Micro-grinding of titanium

    Author : Mohammadali Kadivar; Chalmers University of Technology; []
    Keywords : dressing; grinding; tool topography.; modelling; Micro machining;

    Abstract : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. READ MORE

  2. 2. Aspects of creep-fatigue in gas turbine hot parts

    Author : Magnus Hasselqvist; Gunnar Härkegård; Linköpings universitet; []
    Keywords : creep; fatigue; TMF; gas turbine; modelling; life assessment; ageing; micro-structure; solute drag; back stress; Haynes 230; IN792;

    Abstract : The goal is reliable creep-fatigue lifing methodology for industrial gas turbines.A literature study on high temperature materials used in gas turbines reveals that:• Most testing/modelling work has focused on characterisation and modelling of material response in isothermal standard tests, i.e. creep, tensile and LCF tests.
