Aluminum Alloy A352 Lab Report

The following simulations were carried out on Aluminum alloy A356 to determine the effect of initial temperature of the billet on the forging load. The simulations were carried out at different temperatures between the solidus and liquidus temperature range of the alloy. The position of the billet on the bottom die was determined by placing it in different positions and also for various temperatures. The present location was finalized after studying the aspect of under filling of die cavity and also...

Lab 4 Memo

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 -31ºC...

Iodination of Acetone

Lab Report Iodination of Acetone Temperature as a Variable Objective The objective of this lab is to determine the energy of activation of the iodination of acetone. This will be done by performing the reaction at differing temperatures. The same reaction orders we obtained for the previous lab will be incorporated into this experiment. The equation Ea = -8.31 x slope of ln k vs. 1/T(K) will be used to determine the energy of activation required for this this reaction. Hypothesis...

Aim To investigate the effect of different temperatures on the activity of rennin in milk Introduction Enzymes are globular protein, responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon, hydrogen, oxygen and nitrogen (Gunsch, 2012). The role of enzyme is to act as catalysts, substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done...

Ch205 Lesson 5

mixing, the temperature of the water is 60ºC. * a. How much did the temperature of the hot water change? How much did the temperature of the cold water change? Compare the magnitudes (positive values) of these changes. 200g of water at 80°C = hot water 100g of water at 20˚C = cold water After mixing the temperature is 60˚C (equilibrium T) Answer: The temperature of hot water changed: 60˚C - 80˚C = -20˚C The temperature of cold water changed: 60˚C - 20˚C = 40˚C The temperature change hot...
