SUBJECT: Temperature-dependent impact tests on AISI 1018 steel and 6061 Aluminum Purpose This lab was performed to fully comprehend the temperature dependency of the fracture toughness of the Aluminum and Steel. It was also executed to discover the ductile-brittle transition of each. Summary The experiment solidified the hypothesis that the 6061 aluminum has no ductile-to-brittle transition do to its FCC crystal structure. The 1018 steel has a ductile-to-brittle transition temperature of

The dry type magnetic separator is commonly used iron ore and manganese ore beneficiation equipment. It is the mainstream strong magnet separator‚ which is specialized in processing dry magnetic minerals. The wet type magnetic separator use liquid diluents to improve separation efficiency. The dry type magnetic separator requires that the material must be dry‚ and can move freely between the particles. Or it will affect the separation result‚ and even cannot separate materials. The magnetic system

Purpose: The purpose of this lab is to investigate the reliability of the activity series of metals by testing in solution‚ confirming if the activity series was correct with its predictions. Hypothesis: It is predicted that the metals in solid form will displace metals in solution if located higher over the other within the activity series chart. Materials: 10 test tubes Test tube holder Metals in Solid Form 1. Aluminum 2. Iron 3. Zinc 4. Magnesium 5. Zinc 6. Aluminum 7. Copper

Review on Alcoa ’s Core Values in Practice Porsha Jones BUS250 Jana Radley-Killeen June 16‚ 2014 Alcoa was established in 1888 under the name of the Pittsburgh Reduction Company‚ later on in 1907‚ changing it ’s name to Aluminum Company of America (Alcoa). In a few years time‚ Alcoa had industrialized into a broad vertical integration with complete input control over aluminum production. This company ’s value-based culture was solid. According to Alcoa‚ “ In all of our operations‚ our values

Data: Mass of aluminum foil 1.033g Mass of filter paper 0.472g Mass of Al crystals‚ filter paper‚ weight boat 20.823g Mass of weigh boat 2.064g Mass of Al crystals 18.287g Claim: Based on my calculations‚ the theoretical yield of Aluminum was 18.160g‚ and the actual yield was 18.287g. This gives a percent yield of 100.699%. Evidence/ Reasoning: By looking at the overall

Percent Mass of Copper in a Penny Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies. The composition of a standard penny is 97.5% Zn and 2.5% Cu. In the lab we will be using Beer’s Law (A=elc+b where A is solution absorbance‚ e is a constant called molar absorbency‚ l is the length in cm‚ and c is the concentration). Using Beer’s Law in this

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum
