Fe‚ Ni‚ Co and Cr were present in more than 65 % in the residual fraction‚ while Mn was around 40 %. Next to the residual fraction‚ Mn‚ Ni and Co were present in the Fe-Mn oxide fraction‚ while Fe and Cr in the organic bound fraction. Metals viz. Fe‚ Ni‚ Co and Cr were available in least concentration in the carbonate fraction. Manganese was least in the organic bound

with the standards. The purpose of this experiment is to analyse the hardenability of the three materials such as EN-3 (1015)‚ EN-8 (1040) and EN-24 (4340). 1.2 Objectives The test has following objectives‚ to check the hardenability of different metals‚ the effect of carbon on the material’s hardenability and the comparison of the link between the microstructure and the cooling rate [1]. 1.3 Additional Comments The results are plotted as functions of distance from the quenched end‚ yielding hardenability

Environmental problems in the Philippines There are few signs today of the Philippines’ once sprawling rainforests. With a growing trend in human population‚ it is hoped that the country’s marine environment will not suffer the same fate. Overfishing and destructive fishing Fishers in the Philippines are increasingly coming home with pitiful catches. Of a number of factors which have led to this situation‚ one stands out: over-fishing in many areas. According to the Asian Development Bank

Gold is a soft metal that is largely unreactive. Gold jewellery can lie underground for thousands of years and emerge shiny after that lengthy exposure to air‚ water‚ and other chemicals in the environment. Gold does dissolve in some solvents as indicated below and does react with halogens. The most common oxidation states of gold are Au(I) and Au(III) but there are a few examples of Au(V) (various anions [AuF6]- and [Au2F10]). The Au(III) ion has the d8configuration which gives rise to many square

element in the periodic table‚ it is in period 4‚ group 16 which is also called the chalcogen group. The term chalcogen stands for “sulfur”‚ therefore all elements in family 16 are similar to the element sulfur. All the elements in family 16 are non-metals and all of these elements in chalcogen family have six electrons in the outermost shell so they all have the similar properties. Give a description of the physical characteristics and chemical properties of the element. Physical characteristics:
