Abstract-In this investigation, AA6061 milled particle size was fabricated by milling machine and later compacted by hydraulic press in room temperature. Seven specimens were chosen for the heat treatment process. For reference, one specimen was treated solely by the quenching and another one was treated by the aging only, On top of that, there were five specimens were subjected to various holding times during the aging. The experimental results show that the maximum value of compression strength was 300.47 MPa for the specimen subjected to quenching and aging of holding time 4 hours and the maximum value for microhardness was 100.44 Hv for the same specimen. While the density value was decreased with increasing the holding time. The maximum value of the density was 2.61 g/cm 3 for the specimen (Quenching only). X-ray inspection was detected some of chemical compound were created such as (Al86Fe14) and (Cr13Ni5Si2). Keyword-Aging process, Milling process, Powder metallurgy, Recycling aluminium, AA6061.I. INTRODUCTION 6xxx Al-Mg-Si alloys have been widely used in automotive body panels as main substitute materials for weight reduction [1]. The industry has been focused on the materials as recycling, specifically the materials have been used more and more costly. These recycling offers several advantages which include their relatively lower production costs, isotropic properties and the possibility of using conventional shaping methods (e.g. Extrusion, forging, and rolling) for component manufacturing [2]. Among the various physical and chemical methods, a mechanical ball-mill technique is recognized as a simple and cost-effective method to produce fine and homogeneous powders [3]. During the past 20 years, high energy ball milling has extensively been utilized as a versatile method to produce a variety of advanced compound powders. The main difference between high energy milling by the planetary ball mill, Spex, Attritor mill, etc. and conventional milling is that the former applies much larger doses of energy to particles over time [4]. This large input energy makes high energy mills capable of producing materials with special properties that could not be synthesized by other methods. The milling process produces considerable strain hardening in the Al powder, which is directly reflected on the final properties of the composite powders, therefore, it is needed to treat with heat treatment process [5]. A commercial AA6061 aluminum alloy is one of the Al, Mg, Si(Cu) system alloys that can be significantly hardened by a proper heat treatment. Because of its medium strength, excellent corrosion resistance, and weldability, the AA6061 alloy has been widely used as structural material for construction, transportation and sports [6]. (Lipeng et.al.2015) has been treated aluminium AA6022 by various aging temperature (80, 100, 130 and 170 °C) and various holding times (2,3,4 hrs). He has concluded that the 100 °C by 3hrs is the best attempt. Other than that, there were researchers had been published some other research ...

Composites of a Ti-C-H-Cu system were obtained by mechanosynthesis in liquid carbon media (petroleum ether, xylene) followed by magnetic pulse compaction of the powders at 500°C in vacuum with the pressure amplitude of about 1.5 GPa. The chosen proportion of the components (Ti, Cu) corresponded to the composition TiC (90 vol%) -Cu (10 vol%). In addition, composites containing Cr and / or Ni with the atomic ratio of concentrations Cu : (Cr,Ni) equal to 80 : 20 were obtained. The compacts obtained had the diameter of 10 mm and thickness of 3 to 5 mm. The structure and phase composition of the composites were studied and density, microhardness and wear resistance were determined. The composites processed had the density of 87 -95 % of the theoretical value. The mechanosynthesis process in petroleum ether is not complete in 3h, since in the phase composition of compacts one observes, apart from intermetallic phase CiTi 2 and titanium carbohydride Ti 2 CH 0.6 , a significant amount of the initial Ti. The composites exhibit a layered microstructure. Use of xylene for mechanosynthesis process of the same duration allows one to obtain two-phase composites Ti 2 CH 0.6 + CuTi 2 . An increase of the duration of mechanical treatment up to 6 h leads to a formation of intermetallic CuTi in the phase composition of the composites obtained. Use of xylene allows one to obtain also 10 -20 vol% of nonstoichiometric carbide TiC. The microhardness of about 5 GPa was obtained for all the composites studied. Abrasive wear of the composites is an order of magnitude lower than that of steel U13. Alloying with Ni and / or Cr leads to some decrease of wear resistance due to a decrease of the quantity of TiC phase.

This paper describes a novel mixing method together with mixing device. The Micro Pulse Mixer ( ) PM µ has been designed, constructed and tested using a new mixing concept based on damped harmonic oscillator motion. Advantages of the technique include simplicity of the device, high rates of mixing and high uniformity of product. Furthermore, the device design, with discrete powder containers, allows rapid loading and unloading of samples ( ) 60s -30 enabling powder sampling and/or complex blending operations. The mixer does not require frequent cleaning. It is designed to mix relatively small volumes of powders (up to several grams) for use in either laboratory work or for small commercial samples of high value.In this study we compared the PM µ method with rotating tumbling mixing.Mixing products were evaluated by analysis of scanning electron microscope (SEM) images while X-ray diffraction (XRD) was used to monitor phase evolution A. M. AKSENCZUK et al. 78 during mixing. Powder particle distributions were obtained based on image analysis techniques with mixing efficiency parameters determined based on the calculation of the percentage compounds content within sampled powder is proposed.We believe that the more efficient approach of impulse mixing could be beneficial for laboratory purposes and as a simple and cost-effective powder mixing and blending method.
