“…Reinforcing the ductile aluminum matrix with stronger and stiffer second-phase reinforcements like Al 2 O 3 , SiC, AlN, Si 3 N 4 , Al 4 C 3 and TiC provides a combination of properties of both metallic matrix and ceramic reinforcement components resulting in improved physical and mechanical properties of composite [6][7][8][9][10][11]. Al 2 O 3 is known as a suitable reinforcement for the Al matrix since it is chemically inert with Al and can be also used in higher temperatures, in comparison with the un-reinforced aluminum, with accompanying benefits of resistance to creep [12].…”

“…These enhancements are commonly due to the added ceramics particles [2,5,6]. Studies in recent years, another class of material, namely the composite materials, are becoming increasingly important [7]. A composite is a structural material that generally consists of two or more combined constituents that are combined at a macroscopic level and are not soluble in each other [8][9][10][11].…”

In the present study, weldability of Alumix 231 based composite materials reinforced with Al 2 O 3 and B 4 C and produced by powder metallurgy route is investigated. Various amounts of (0, 5, 10, and 15% wt.) Al 2 O 3 and B 4 C powders are added to the pre-alloyed Alumix 231 (Al-2.5% Cu-0.5% Mg-14% Si) powders separately and then mixed in a three-dimensional mixer for 45 min. Powders are compacted and sintered in an argon atmosphere at 640C for 4 h. Produced blocks are welded by the Tungsten Inert Gas (TIG) welding at 25 V, 197 A and 14 l/min shielded gas flow in commercially pure argon atmosphere. Macro-and microexamination together with some mechanical properties of the welded area are studied. The results show that, although high amount of particles resulted in a decrease in the density, these composite materials can still be welded by the TIG welding method successfully.Исследуется свариваемость произведённых методом порошковой метал-лургии композитных материалов на основе Alumix 231, армированных Al 2 O 3 и B 4 C. Различные количества (0, 5, 10 и 15 масс.%) порошков Al 2 O 3 и B 4 C по отдельности добавлялись в предварительно сплавленные порош-ки Alumix 231 (Al-2,5% Cu-0,5% Mg-14% Si), а затем перемешивались в трёхмерном миксере в течение 45 минут. Затем порошки прессовались и спекались в атмосфере аргона при 640C в течение 4 часов. Полученные блоки сваривались вольфрамовой сваркой в атмосфере инертного газа при 25 В, 197 А и потоке инертного газа в 14 л/мин в атмосфере технически чистого аргона. Были проведены макро-и микроисследования некоторых механических свойств сварной зоны. Их результаты показали, что, хотя оказалось большое количество частиц с пониженной плотностью, эти композитные материалы могут быть успешно сварены методом вольфра-мовой сварки в атмосфере инертного газа. 1314 H. ATES, U. GOKMEN, H. CINICI, A. UZUN, H. KARAKOC, and M. TURKER у попередньо стоплені порошки Alumix 231 (Al-2,5% Cu-0,5% Mg-14% Si), а потім перемішувалися в тривимірному міксері впродовж 45 хвилин. Потім порошки пресувалися та спікалися в атмосфері арґону при 640C впродовж 4 годин. Одержані блоки зварювалися вольфрамовим зварен-ням в атмосфері інертного газу при 25 В, 197 А та потоці інертного газу у 14 л/хв. в атмосфері технічно чистого арґону. Було виконано макро-та мікродослідження деяких механічних властивостей зварної зони. Їх ре-зультати показали, що, хоча виявилася велика кількість частинок зі зниженою густиною, ці композитні матеріяли можуть бути успішно зва-рені методою вольфрамового зварювання в атмосфері інертного газу.

“…[1] Al-based matrix composites (AMCs) have found several applications mainly in aerospace and automotive industries due to their processing flexibility, low density, high wear resistance, heat treatment capability, and improved elastic modulus and strength. [2][3][4] These composites are produced via different routes mainly casting [5][6][7] and powder metallurgy. [8] The casting methods are simple and economical due to the possibility of utilizing the conventional casting equipments without limitation in size and shape of the components.…”

In this investigation, the effect of hot extrusion process has been studied on the microstructure and tensile properties of aluminum matrix composite containing different amounts (10, 15, and 20 wt pct) of Al 4 Sr intermetallic phase. Microstructural examinations assessed by scanning electron microscopy revealed that hot extrusion breaks large Al 4 Sr particles and reduces their length tremendously. It was also found that although the addition of Al 4 Sr content in the composite reduces ultimate tensile strength and elongation values, hot extrusion improves tensile results significantly. Remarkable result of this study was concerned with significant improvement in the toughness of hot-extruded Al-10 wt pct Al 4 Sr composite in which elongation values raised up to 22 pct. Therefore, optimum amount of Al 4 Sr intermetallic in the composite was found to be 10 wt pct. Fractographic examinations revealed that hot extrusion encourages ductile mode of fracture by introducing homogeneous distribution of fine dimples on the fracture surface of the composites.
