Abstract This study investigated the impact of equal channel angular pressing (ECAP) combined with heat treatments on microstructure and mechanical properties AlSi10Mg alloys fabricated via selective laser melting (SLM) gravity casting. Special attention was directed towards determining effect post-fabrication microstructural evolution alloy using two different routes. Three initial conditions ...

Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP) at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 2...

Abstract. The excellent performance of duplex and super stainless steels due to their high corrosion resistance mechanical strength is directly related austeno-ferritic microstructure. However, these may suffer the formation secondary brittle phases when they reach temperatures between 600°C 950°C causing catastrophic service failure components. In order understand influence history steel, equa...

over the last two decades, many researchers have developed a variety of stainless steel-based medical implant types,taking full advantage of nanostructuring technologies. in this paper the application, fabrication and development of nanostructured stainless steel based materials with new composition for medical implants will be discussed. it is well established that application of severe plasti...

Bauschinger test in uniaxial tension-compression mode was carried out for the first time on pure Al specimens having homogeneous ultra-fine grained (UFG) microstructures fabricated by equal-channel angular pressing (ECAP) and subsequent annealing processes. Significant stress (transient softening), energy parameter their strong dependences tensile plastic pre-strain at very early stage of defor...

Equal channel angular pressing has been used to refine the grain size of commercially pure titanium (grade 2) as well as other metals and alloys. Titanium grade 2 is usually processed at about 350 °C because it lacks sufficient ductility at lower temperatures. The warm processing temperature limits the capability of the equal channel angular pressing technique in improving the strength of titan...

In this paper, we study the strength and fracture mechanism of cast magnesium alloy Mg-Zn-Ca (1.0 % Zn, 0.2 Ca) for medical applications after equal-channel angular pressing (ECAP) in comparison with initial condition (after homogenization annealing). Mechanical tests included tensile torsion samples a diameter 3 mm impact V-shaped stress raiser. The microrelief all fractures was studied Phenom...

Commercially pure nickel was processed by equal channel angular pressing (ECAP) through route Bc for 12 passes to obtain an ultrafine grained (UFG) microstructure and further subjected to an ultrasonic treatment (UST) which introduced a maximum amplitude equivalent to anormal stresses of 100 MPa in a steady state regime. It was observed that the microstructure of UFG Ni can be differently alter...
