Lab report

Abstract The objective of this experiment was to determine the influence of phase transformation on the microstructure and mechanical properties of plain carbon steel type AISI C1045. The testing of metals is necessary to learn what metal is suitable for construction of a specific item by testing how microstructures react during phase transformations. The metal used during the experiments was samples of AISI C1045 Steel also called carbon steel alloy. The samples each underwent tests for Heat Energy (ft-lb) and Hardness (HRC) at five temperatures; 70°F (assumed to be room temperature, 400°F, 700°F, 1000°F and ...

Extraction Stage

Extraction of copper produces both specks of dust and gaseous wastes such as sulfur dioxide and carbon dioxide that significantly contribute to environmental pollutions, especially air pollution (“Copper Mining”). Whereas copper wire miners reduce this pollution level by trapping the generated sulfur dioxide gas for purposes of producing sulfuric acid, considerable amounts of sulfur dioxide still escape and take part in both air and water pollution. However, extraction methods that incorporate emulsion of liquid membranes and applications of microorganisms in removing copper from their underground ores have been currently established as the economical and viable ways of gathering copper. ...

Introduction

Stainless steel is an important component in the modern industry having various uses in the industry. This has forced new developments in its manufacturing especially in terms of its composition. This can be the steel made from aluminum, manganese, and iron. All these materials makes the finished stainless steel product unique in terms of its composition, physical metallurgy, and other factors. This paper is going to discuss the development in stainless steel technology with regards to its composition in terms of the materials used. The materials that are going to be discusses are Al, Mn, and Fe. The paper ...

Introduction

For one to achieve success in any given casting practices, there must be a proper control in the variables required during the process. The variables may involve certain characteristics of the alloys, and metals used, the casting method, design of the mold, material of the die used, and the parameters used during processing. The casting quality is influenced by the cooling rate, gating systems, and the evolved gasses during the entire process. Precautions must be, therefore, taken to avoid defects during metal casting design. This paper also outlines the economic factors that are relevant and basic in casting operations.

Metal casting

...

For a casting process to be successful, various variables will need to be controlled. These variables will range from the characteristics of the metals, or the alloys, the specific method of casting, the molten metal materials and design and other process parameters. Others like the flow of the molten metal in the cavities, the gating systems, the gases evolved, and the cooling rate of the molten metals will influence its quality. This paper is going to discuss the design consideration in casting, the selection of the material processes, selection of the casting process, inspection and problems in casting and ...

Introduction

Stainless steel is an alloy with iron as major part and chromium with at least 11% by weight . Stainless steel industry grew rapidly during the 1989-93 period . This paper analyzes stress corrosion of stainless steel along with prevention measures and selection methods for stainless steel. After carrying out the study, it would be established whether stainless steel is an effective alloy or not for major uses in steel industry through adopting various selection parameters. Stainless steel is called stainless due to the resistance to rusting and corrosion .

Stress-corrosion in Stainless Steel

In order to reduce various occurrences of intergranular stress-corrosion cracking and severe ...

Abstract

Titanium metal is mainly used in the automotive industry due to its high-temperature resistance, high strength, resistance to wear and corrosion, and the unique properties of its alloys. Titanium applications in exhausts systems are the key attractive entry point of the metal into the automotive industry. The applications of titanium and its alloys in the automotive industry in making exhausts systems has been in existence for quite some years. Its application is supposedly limited to the first class road models and the racing cars because of its temperature capability and the cost.With the recent modification of titanium by alloying ...
