Mechanical behaviour of tools for shearing Ultra High-Strength Steels: influence of the microstructure on fracture and fatigue micro-mechanisms of tool steels and evaluation of micro-mechanical damage in tools
Picas Anfruns, Ingrid (Universitat Politècnica de Catalunya, 2012-12-10)
Tesi
Accés obertOn account of environmental and safety related requirements, the majority of the most popular automotive manufacturers convey to introduce Ultra High Strength Steels (UHSS) and Press Hardened Steels (PHS) in the vehicle ... -
Micro-mechanical damage in tool steels analyzed by acoustic emission technique
Picas Anfruns, Ingrid; Martínez González, Eva; Casellas Padró, Daniel; Romeu Garbí, Jordi (2012-12-30)
Article
Accés restringit per política de l'editorialThe carbides in tool steels act as hard particles and dictate the wear resistance. The origin of failure of these steels is mostly related with the carbide cracking, as a nucleation site of final cracks. This paper shows ... -
Microstructural effects on the fatigue crack nucleation in cold work tool steels
Picas Anfruns, Ingrid; Cuadrado, Núria; Casellas Padró, Daniel; Goez, Alexey; Llanes Pitarch, Luis Miguel (2010-04)
Article
Accés restringit per política de l'editorialCrack nucleation mechanisms in two types of cold work tool steels were evaluated under monotonic and cyclic loading conditions. The effect of the microstructural constituents: the primary alloy carbides and the tempered ... -
R-Curve approach to describe the fracture resistance of tool steels
Picas Anfruns, Ingrid; Casellas Padró, Daniel; Llanes Pitarch, Luis Miguel (2016-06)
Article
Accés obertThis work addresses the events involved in the fracture of tool steels, aiming to understand the effect of primary carbides, inclusions, and the metallic matrix on their effective fracture toughness and strength. ...
