Report on High Entropy Alloys(HEA) Introduction: Alloys can be defined as a mixture of two or more elements containing one or more elements containing one metal at the least. From bronze age ‚ alloys have been developed based on one principal element. Later metal matrix composites and inter metallic compounds gained attention. Development in technology and innovation lead to the idea of multicomponent system. These systems consists of multiple principal elements. This was attained by alloying

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce

Recommendation Although aluminum prices are at relative historic low today‚ we recommend that Alusaf go ahead with plans to construct the Hillside smelter plant. Based on the following analyses‚ we project the price of aluminum to rise to approximately $1‚590 per ton in 5 years. This price exceeds the minimum required level of $1‚416 per ton to yield Alusaf a positive net present value (NPV) on its initial plant investment of $1.6 billion. Analysis of Hillside plant profitability At a minimum

The Aluminum Industry in 19941 and Aluminum Smelting in South Africa: Alusaf’s Hillside Project2 1) Is primary aluminum production an attractive industry? Why or why not? Within the framework of the Structure-Conduct-Performance (SCP) model3‚ the primary aluminum production industry (“the industry”) in 1994 can be described as perfectly competitive. The industry is characterized by a large number of competing firms – the largest of which has only 4.1% of total industry capacity; homogeneous

Shape Memory Metal The goal of the experiment was to heat the shape memory alloy to see if the metal will revert back to its original shape. In order to do so I needed a hair dryer with a low and high setting‚ and a shape memory paperclip. How I went to test this was I took the paper clip‚ straightened it out‚ and then heated the paper clip with the blow dryer. In order to obtain accurate results‚ I needed to do four trials with the blow dryer on the high setting‚ and one trial with the blow

its defeat to aluminum‚ included the fact that it could only be rolled thicker than aluminum; it became brittle when warm‚ reducing its malleability greatly‚ and the tin foil created a strange aftertaste‚ which was undesirable to many. During the beginning of the 1800s‚ scientists and companies began to experiment with aluminum foil. Reynolds Wrap‚ started by Richard Reynolds‚ became the first company to use aluminum foil instead of tin. His reasons were simple and logical: aluminum rolled thinner

Aluminum is the third most plentiful element in the earth’s crust. It is the second most widely used material in new cars and trucks in the world. Before aluminum foil was invented‚ food and other items were packed in tin foil. However‚ tin foil was too stiff to be malleable‚ and some experts feared that it might affect food adversely. History Although others have vied for the honor‚ history credits Hans Christian Oersted‚ a Danish chemist for the initial discovery of aluminum foil‚ 1n 1825. On
