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...

The geometrical structuring of a material to increase both physical and mechanical qualities is known as Severe plastic deformation (SPD). To obtain superior qualities, the co-channel angular (ECAP) approach, which an alternative conventional deformation, applied developed. When compared previous procedures, substan- tially smaller grain size obtained result applying large unit defor- mation pa...

In recent years, the fabrication of bulk materials with ultra fine grain sized materials processed by SPD methods. Different techniques have been used to introduce large plastic strains in to bulk metals such as Equal Channel Angular Pressing (ECAP) [1-3], Accumulative Roll Bonding (ARB) [4-7], Repetitive Corrugation and Straitening (RCS) [8,9], Constrained Groove Pressing (CGP) [5] and Constra...

Equal-channel angular pressing (ECAP) was one of severe plastic deformation method in order to increase the mechanical properties solid metal without changing its dimension and adding any alloy elements. The change on ECAPed metals caused by lattice strain, so that strain investigation recommended for evaluating metals. In this study, pure titanium rod treated ECAP with Bc route two passes. Bef...

In the selective laser melting process (SLM), region irradiated by beam is melted and quickly solidified, forming solidification lines (laser scan tracks) with symmetrical shapes. Because of unique (rapid) crystallization conditions, subgrain structures, typically observed inside these lines, could also have variable geometric patterns, e.g., cellular, pentagonal, or hexagonal cellular. The exi...

Abstract In recent years, a number of studies in Non-Destructive Evaluation (NDE) have been conducted on the sensitivity probes assessing depth cracks based input stimulation. Range frequency and crack suggested as relevant features for excitation waveform forms. The construction an encircling coil differential probe (ECDP) absolute (ECAP) was discussed this paper. For defect, Multi-Frequency (...
