These incorporate change of mass machines due to wear and fail of lubrication. Friction is main properties of the materials, surface medications and cause of wear and energy dissipation. Improving friction can utilization of covering, and so on. In the course of the most make substantial saving. It is obvious that enormous amount recent couple of years, numerous endeavors have been made of the worlds resources are used to overcome friction in the to comprehend the wear conduct of the surfaces in sliding form or another. Lubrication is an effective means of contact and the instrument, which prompts wear. The controlling wear and reducing friction. Hence, for the survival applications of aluminium and its alloys for the machine of machine wear and friction must be decreased parts are increasing day to day in the industry.

COMPLEX & INCREMENTAL STRESS CREEP OF A HIGH STRENGTH ALUMINIUM ALLOY AT ELEVATED TEMPERATURES (ALLOY: HIDUMINIUM RR58 SPECIFICATION DTD 731) by SURINDAR BAHADUR MATHUR Thesis presented in the Department of Mechanical Engineering for the Award of the Doctor of Philosphy in Mechanical Engineering of the University of London. Mechanical Engineering Department Imperial College of Science and Technology mAec.19 70 (University of London) London. ABSTRACT A theory for creep rates under complex and incremental stresses is deduced from experimental data concerning complex creep at elevated temperatures for the test material HIDUMINIUM RR 58 - Specification DID 731. The most important results are for tubular specimens tested at 150°C and 250°C under incremental loads. The analysis of results relates to steady state creep only. Modified relationships in stress equivalence and strain equivalence are proposed to account for thermal softening, polygonization, recrystallization and the resulting exaggerated flow in the direction of the applied shear. (The original equations are based on the hypothesis of Von Mises). A further relationship is suggested between the immediate total energy of distortion and the subsequent creep work rate. Results of the static tests and the results of the tests for creep behaviour under complex loading are presented and compared with the results of static torsion and simple incremental torsion creep tests on the basis of the proposed equations. An appendix describes the complex creep testing machine, furnace, extensometers -

Alkathafi1*, Abdalfattah A. Khalil2, Ayad O. Abdalla3 Affiliations: 1Mechanical Engineering Department, Faculty of Engineering, Sirte University, Libya 2Materials Science Department, Faculty of Engineering, Omer Al-Mukhtar University, Libya. 3College of Mechanical Engineering Technology, Benghazi-Libya. *Corresponding author: Maftah H. Alkathafi* Mechanical Engineering Department, Faculty of Engineering, Sirte University, Libya Received: December 10, 2020 Published: December 31, 2020 Abstract: In this study a fast-cooling technology is employed for a cast iron mould to prepare cast A356 aluminium alloy by solidifica- tion of the molten metal. The cooling rate is achieved by pouring the molten alloy into a preheating permanent mould at different temperatures (25, 100, 200, 300 and 4000C) for cast samples with 40 mm inside diameter and 200 mm height. The samples considered are analyzed by optical microscopy, scanning electron microscopy (SEM), and EDS X-ray analysis (EDS). The effects of cooling rate on the morphology of α – aluminum and eutectic silicon of A356 alloy have been studied. The results showed that the dendritic structure of α-phase was broken and converted into a somewhat globular grain structure and the coarse acicular eutectic silicon trend to be broken and converted into short sticks or small rounded in other cases. Keywords: A356 Aluminum alloy, Grain refinement, Cooling rate, SEM, EDS, Microstructure. 1. Introduction Aluminium alloys have attractive physical and mechanical properties. They are lightweight, low costs production, easy to machine and have good recycling possibilities up to 95 % [1]. -

Metals and ceramics, as well, can be embedded with particles or fibers, to improve their properties; these combinations are known as Metal-Matrix composites. Aluminum 7075 alloy constitutes a very important engineering material widely employed in the aircraft and aerospace industry for the manufacturing of different parts and components. It is due to its high strength to density ratio that it a sought after metal matrix composite. In this paper we present a survey of Al 7075 Metal Matrix Composites. Keywords: Metal Matrix Composites (MMC’s), Aluminium Metal Matrix, Beryl, Al7075, Aluminium alloy 1. Introduction Aluminium alloy 7075 is an aluminium alloy, with zinc as the primary alloying element. It is strong, with a strength The effects of research in Aluminium based Metal Matrix comparable to many steels, and has good fatigue strength and Composites (MMC’s) are far reaching these days. These average machinability, but has less resistance to corrosion composites find various applications in the automobile than many other Al alloys. Its relatively high cost limits its industry, the aerospace industry and in defence and marine use to applications where cheaper alloys are not suitable. -
