Provide a 8 pages analysis while answering the following question: Aerospace Material and Component Testing Techniques. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Hardness involves a material property, which enables it to have resistance to plastic deformation, normally through penetration. This term can also refer to the abrasion, bending, cutting and scratching resistance. The material’s hardness can be assessed by measuring the scratching or cutting resistance. In minerals, relative hardness can be assessed using a reference to the Mohs Scale that ranks the potential of a material to have resistance to the scratching of another material. Other methods that can be used to assess relative hardness include the file test, in which a tempered file to the desired hardness is rubbed on the material surface of a test. If this file slides with no biting or marks the surface, the test material is said to be extremely harder than that file. If the file marks or bites the surface, the material test is said to be softer than that file. Other methods of achieving a value of hardness involve measuring the area or depth of a left indentation by an indenter or a shape that is specific with a particular force applied for a particular time. In this case, the three standard methods used in giving out the relationship between the impression size and hardness include Vickers, Brinell, and Rockwell. Each of the test methods is categorized into scale ranges that are defined by an applied combination of indenter and load geometry.
Tensile testing can also be referred to as tension testing. This is a basic material science test, whereby a sample is set into a controlled tension up to when a failure is obtained. The test results are mostly used in selecting a material for a quality control application and in predicting how a material reacts under other different categories of forces. Some of the traits that are measured using tensile testing include ultimate tensile strength, area reduction, and maximum elongation.
