چکیده
This paper presents the results of studies on true fracture stresses Al alloy 6101 with an ultrafine-grained (UFG) structure processed by equal channel angular pressing — conform (ECAP-C) method and same after artificial aging (AA state). The grain size in UFG state was about 500 nm. Aging particles Al3Fe were present AA state. Strength yield stress increase as a result formation structure. strain to failure states alloy, taking into account measurement error, is same. In this case, samples markedly higher than An explanation for specimens based generalization Hall-Petch relation Zener-Strauss model, criterion pore particle, proposed.

Development of microstructure and fracture toughness of AL-6063 alloy using equal channel angular extrusion
Severe plastic deformation (SPD) is one of the processes used to refine the microstructure of materials. Equal Channel Angular Extrusion (ECAE) is the most common method of SPD. In this study, AL-6063grain refinement was performed using the Equal Channel Angular Extrusion method. The material was extruded up to 6 passes at a temperature of 200°C following route A. A suitable die sets equipped w...
متن کاملFracture Analysis of High Strain Rate Torsion Samples of Aluminium Zinc Magnesium Copper Alloy
All materials have been historically tested at static loading conditions. With the advent of technology, the study of behaviour of materials at high strain rate was done using various methods. The principle of split Hopkinson bar was used to study high strain rate of material in the range of 102s-1 to 103s-1. Split Hopkinson bars were designed for all three modes of deformation and extensively ...

The tensile fractures of ultrafine-grained (UFG) Al-Mg alloy with a bimodal grain size were investigated at the microand macroscale using transmission electron microscopy (TEM), scanning electron microscopy (SEM) equipped with focused ion beam (FIB), and optical microscopy. The nanoscale voids and crack behaviors near the tensile fracture surfaces were revealed in various scale ranges and provi...

Physical phenomena underlying failure due to electromigration and stress-induced voiding in fine AI and AI-alloy thin-film conducting lines are examined in the context of accelerated testing methods and structures. Aspects examined include effects due to line isolation (the absence of reservoirs at conductor ends), solute and precipitate phenomena, conductor critical (Blech) length, microstruct...
