   Abstract : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. READ MORE

3. 2. Towards the measurement of two independent viscoelastic functions using spherical indentation

   University essay from KTH/Hållfasthetslära (Inst.)

   Author : Hassan Mohammad; [2016]
   Keywords : ;

   Abstract : Instrumented indentation is a promising testing technique for obtaining the time dependent viscoelastic properties of bitumen and bitumen-based mastics. It offers several advantages: controlling the length scale of measurement and thus could be used in multi-scale modelling of asphalt, the possibility of in-situ tests and the minimal requirements of sample preparation.

4. 3. Measurement of Bitumen Relaxation Modulus with Instrumented Indentation

   University essay from KTH/Väg- och banteknik

   Author : Trinh Ngoc Phan; [2012]
   Keywords : Instrumented indentation; Viscoelasticity; Spherical indenter; Relaxation modulus.;

   Abstract : Instrumented indentation testing was used to determine viscoelastic properties of bitumen, i.e. shear relaxation modulus. Review of previous studied reveals that indentation testing technique has been drawing increasing attempts in investigations of binder material mechanical properties. READ MORE
