Two different bainitic structures are observed in a steel depending on the sample
heat treatment. The different types of bainitic structures exhibit different orientation
relationships between cementite and the ferrite ...
Fracture toughness of polypropylene-based particulate composites
(Molecular Diversity Preservation International, 2009-11-30)
Article.
Accés obert
Article.
Accés obert
The fracture behaviour of polymers is strongly affected by the addition of rigid
particles. Several features of the particles have a decisive influence on the values of the
fracture toughness: shape and size, chemical ...

Accés restringit per política de l'editorial
Low-grade magnesium hydroxide (LG-MH) is a solid by-product that undergoes an endothermic
decomposition in the temperature range of 300–750 C. Due to its thermal behaviour and its lower cost
relative to pure Mg(OH)2, ...
