The digital image correlation (DIC) technique was utilized in conjunction with mechanical experiments carried out at different strain rates to study the negative strain rate sensitivity (NSRS) in face-centered cubic (fcc) Hadfield steels. The results shed light onto the variation of local strain fields and serrations in the stress– strain curves of Hadfield steels as a function of strain rate w...

Manganese is a standard alloy element in many wrought steels, offering improved strength and hardenability and, Hadfield also unique combination of strength, ductility work hardening behaviour. In sintered steels Mn has been used rarely so far because two reasons: one the high oxygen affinity which promotes pickup during heat treatment inhibits removal part through ‘internal getter’ effect. The...

The track components that are the most heavily loaded from axles of train units switch and rail crossing parts. These parts can be refurbished by welding on suitable types additional materials. Parts made high-alloyed Mn-steel (Hadfield steels) need to meet specific conditions for their welding. For experiment, ESAB OK Tubrodur 14.71 15.65 materials were used. results show feasibility appropria...

This paper reports the capability of a range electromagnetic non-destructive evaluation (NDE) methods to characterise decarburising phenomena in Hadfield steels. Four steel samples were austenitised at 1050 °C for 1, 2, 3 and, 4 hours an air furnace followed by water quenching produce various depths. The decarburisation depth was characterised using hardness profile measurements, optical and sc...

in this paper, the correlation between the surface rumpling and cracking phenomena with twinning mechanism during plastic deformation of hadfield steel has been investigated. the effect of stacking fault energy and the amount of strain are evaluated. the experimental samples with specific amounts of carbon, manganese and aluminum resulting in different stacking fault energies, were produced usi...

Introduction The introduction of the land snail Euglandina rosea, which feeds exclusively on snails, has been implicated as a major factor influencing the decline of the native Hawaiian land snail fauna (Hadfield 1986). It was introduced to Hawaii in 1955 to control populations of another introduced snail, Achatina fulica, the giant African snail (Davis & Butler 1964, Simberloff 1995, Civeyrel ...

Austenitic high-manganese steels (HMnS) offer very high wear resistance under dynamic loading due to their work hardening capacity. However, static abrasive is limited. Various approaches increasing abrasion are known from traditionally manufactured metallurgical components. These confirm the potential for surface protection applications. In this work, powder of Hadfield HMnS X120Mn12 prepared ...
