Journal ArticleDOI
Relationships between tensile and fracture mechanics properties and fatigue properties of large plastic mould steel blocks
Donato Firrao,Paolo Matteis,Giorgio Scavino,Graziano Ubertalli,Maria Giuseppina Ienco,Maria Rosa Pinasco,E. Stagno,R. Gerosa,Barbara Rivolta,Antonio Silvestri,Giuseppe Silva,A. Ghidini +11 more
TL;DR: In this paper, a pointwise determination of the tensile, Charpy V-notched, fracture toughness and rotating bending fatigue properties was carried out in a large block of pre-hardened steel blocks.
Journal ArticleDOI
Microstructural and mechanical characterisation of some sinter hardening alloys and comparisons with heat treated PM steels
G. F. Bocchini,Barbara Rivolta,Giuseppe Silva,E. Poggio,Maria Rosa Pinasco,Maria Giuseppina Ienco +5 more
TL;DR: In this paper, four grades of sinter hardening materials have been compared, using industrial equipment, focusing on porosity, pore shape, hardness, microhardness, microstructure, local chemical composition and mechanical properties.
Journal ArticleDOI
Metallographic Approach to the Investigation of Metallic Archaeological Objects
TL;DR: A wise and careful use of the metallography allows the balance "object sacrifice/knowledge improvement" to lean on the right side contributing to the hard work of rebuilding humankind history.
Journal ArticleDOI
Mechanical twins in 304 stainless steel after small-charge explosions
Donato Firrao,Paolo Matteis,Giorgio Scavino,Graziano Ubertalli,Maria Giuseppina Ienco,G. Pellati,Paolo Piccardo,Maria Rosa Pinasco,E. Stagno,Roberto Montanari,Me Tata,G. Brandimarte,S. Petralia +12 more
TL;DR: In this article, optical, scanning electron, and scanning tunneling microscopy, as well as X-ray diffraction, were employed to detect microstructural modifications caused in AISI 304Cu steel disks by explosions of small charges placed at close ranges.
Journal ArticleDOI
Relation between fatigue crack initiation and propagation, toughness and microstructure in large steel blooms for automotive plastic molds
Donato Firrao,Riccardo Gerosa,A. Ghidini,Paolo Matteis,Giovanni Marco Maria Mortarino,Maria Rosa Pinasco,Barbara Rivolta,Giuseppe Silva,E. Stagno +8 more
TL;DR: A survey of the mechanical properties of some commercial blooms was carried out by using three point fatigue bending tests on notched samples to evaluate the threshold behavior and the crack growth behavior by ΔKdecreasing and ΔK-increasing methods as mentioned in this paper.
