Adaptation of Laboratory tests for the assessment of wear resistance of drill-bit inserts for rotarypercussive drilling of hard rocks

Saai, Afaf; Bjørge, Ruben; Dahl, Filip Erik Bo; Antonov, Maksim; Kane, Pascal-Alexandre; Diop, Jean-Baptiste; Ojala, Niko (Peer reviewed; Journal article, 2020)

The development of wear resistant materials for drill-bit inserts are of primary importance for efficient percussive drilling in hard abrasive rock. To speed up the development of enhanced wear resistance materials, the ...
Assessment of advanced Taylor models, the Taylor factor and yield-surface exponent for FCC metals

Zhang, Kai; Holmedal, Bjørn; Manik, Tomas; Saai, Afaf (Journal article; Peer reviewed, 2019)

High-resolution crystal plasticity-finite element method (CPFEM) simulations are performed to provide new reference values of the Taylor factor M and the isotropic yield surface exponent for high stacking fault energy ...
Multi-scale Modelling of Titanium Diboride Degradation Using Crystal Elasticity Model and Density Functional Theory

Saai, Afaf; Wang, Zhaohui; Pezzotta, Micol; Friis, Jesper; Ratvik, Arne Petter; Vullum, Per Erik (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2018)

Titanium diboride (TiB2) is regarded as the most promising material to be used as inert cathodes in the electrochemical reduction of alumina to aluminium metal. TiB2 is well known as a ceramic material with high strength ...
