Abstract

The present research had dealt with preparing aluminum alloy matrix (Al-4.5%Cu-1.5%Mg) by cast and to proceeding the heat treatment solution from different temperatures 500oC, 525oC and 550oC for different times 2hr and 4hr, and then proceeding the requil hardness (HBR), Therefor we conducted the optimum value from the alloy basic(A) at the temperature 550oC for 4hr time. Also we prepared the matrix composite reinforced by alumina (Al2O3) with different percentage weight (1.5%-2.5%) and three different particles sizes (75µm≥65µm≥53µm≥0.1µm) which named as (A1, A2, B1, B2, C1, C2) according to their weight and size percentages, and then proceeding the heat treatment solution and official ageing about them at the temperature degree 550oC for 2hr and4hr. Mechanical tests like hardness and impact resistance were conducted all of them reached that the composite material (A2) in which there weight and size percentages are 2.5% and ≥0.1µm have upper values of these test's, accordingly we concluded that the reduce particles means increased its rigidity, toughness and solidity. Finally the microstructures tests shows that the prepared composites materials have small size as compared with microstructure of the basic cast alloys and the distribution of alumina particles was fairly homogeneous in the basic allot, also we showed that the heat treatment solutions and official ageing are affected at these composite materials and alloys.

Abstract

This research work includes an experimental study of the mechanical properties , as compressive strength, tensile strength, modulus of elasticity, and stress – strain relation for ordinary concrete. Different mixes of different cement content and W/C ratio considered at different high temperature. Nine different concrete mixes for different cement content and W/C ratio are exposed to four steps of high temperature (20, 200, 400, 600)°C for a duration of one hour. The results show that heating the concrete samples reduces the mechanical properties of the samples in a different percent for different mixes. The affect of high temperatures to modulus of elasticity , splitting tensile strength and compressive strength for concrete are different and various. It has been found that the concrete mixes of low strengths (a few cement and high W/C ratio) maintains compressive strength more than concrete mixes which have high strength (rich cement and low W/C ratio) when exposed to high temperatures. This effects generally vary from mix to another in some or all properties. In general there are less effect at (200°C) degree, then the changes become more sensitive at higher temperature ( 400, 600)°C.

Abstract

Pollution is the most important problems facing the human being at the present time. Air pollution is the most serious problem because of its direct relation to human health and other organisms. Dust samples were collected in some area of city of Kirkuk, depending on several factors such as traffic, industrial and urban activities and population density. The amount of dust deposited and some heavy metals such as Co, Cu, Pb and Fewere determined. The highest value of 148 g / m 2 was recorded for dust in the fifth region / Tergil in April and an average of 111.5 g / m 2, while the lowest value of 8 g / m 2 was for the second region / Al-Mualmeendistrict. High values of the heavy elements especially iron and lead were in April due to dust storm that came into Iraq from neighbor countries and from traffic and industrial activity, especially cement factory as well as the lack of vegetation in the region. High levels of Cu, Co may have sources from Industrial activities, while the main source of Pb ismay be from traffic movement. The results of Geological accumulation factor (I-Geo factor) and contamination factor( CF) as well as pollution load factor PLI indicate the safety of the city of Kirkuk from air pollution by heavy metals with exception of Fe iron and Pb lead in the fifth region.

This study is concerned with the heavy minerals (HM) analysis in the + 63μ m fraction of the Diyala River sediments, distribution pattern in the various river basin sectors, as well as comparing the present results with previous works. The metastable heavy minerals (epidote, staurolite, garnet) represent more than (30%) Whereas the unstable heavy minerals (pyroxene and amphibole) make only about ( 19 %). Opaque's are present in high proportions reaching about (29%) as an average, and decreasing southwards. The Ultra stable (zircon, tourmaline, rutile) heavy minerals are the miner constituents (7%) in the sediments. According to the laboratory analytical data of heavy mineral distributions the studied sediments are derived from several sources for the heavy minerals including igneous metamorphic and sedimentary complexes are found in northeastern Iraq that represent by Walash – Nawpordan Series and Mawat complexes in Zagros zones. As well as the detritus sediments transferred from the rock formations that appears in different parts of the basin, which represented by Fatha(upper Miocene), Injana(Middle Miocene ), Muqdadiya (lower Pliocene), Bai Hassan (upper Pliocene), Kolosh (Paleocene-Early Eocene) and Gercus (Middle Eocene) formations, which were derived from igneous and metamorphic rocks and ancient sedimentary rocks located in to the northeast of Iraq. The presence of Zircon and Tourmaline in trace amounts may give an indication for the weak role of acidic rocks in the source area, whereas the Epidote group minerals give an indication for the role of metamorphic rocks.
