Phases changes of the AK12MMgN-18%SiCp composite alloy after severe plastic deformation and annealing

Abstract: The effect of severe plastic deformation by high pressure torsion (HPT) on the structure of AK12MMgN-18 %SiCp composite alloy was investigated. A liquid-forged billet was taken as an initial material. Samples 8 mm in diameter and 0.45 mm in thickness were deformed by torsion in a Bridgman anvil at room temperature up to 5 turns under the pressure of 4 GPa. After deformation the samples were annealed in the temperature range of 300 -500°C for 5 minutes. The average area and volume fraction of particles in the i… Show more

“…Aluminum alloys are one of the most common types of construction materials, to which various hardening methods are actively applied, including deformation [1] or thermal treatments [2], surface modification [3] and their combinations [4]. Surface modification of aluminum alloys allows one to improve chemical, physical and mechanical properties, regardless of the properties of the base material.…”

“…При этом в Al матрице синтезируются упрочняющие интерметаллидные (армирующие) фазы за счет их зарождения и роста, которые имеют меньшую деградацию при повышенных температурах [1]. Возможности изготовления алюмоматричных композитов по принципу in situ опробовано такими методами как, например, механическое легирование [2], разновидности быстрой кристаллизации [3], сварка трением с перемешиванием [4], интенсивная пластическая деформация (ИПД) [5] и др. Из перечисленных методов интенсивная пластическая деформация наиболее активно применяется для изготовления объемных наноструктурных металломатричных композитов [6].…”
