Introduction

The knowledge of materials is vital for Mechanical Engineers, as when addressing engineering design, at some point will be a need to select the most suitable material for each element designed. The inclusion of the subject of materials essential purpose of responding to suggest solutions to the problems of a professional nature of selection and use of materials that find the Mechanical Engineer in their professional lives.

This report helps to gain the knowledge of the structure of materials, their properties, heat treatment, primary metals and alloys, effects of plastic deformation on structure and properties of materials and failure analysis. In this way the participant is expected to acquire the knowledge necessary to understand and relate the structure and properties of materials, allowing you to make a proper selection of material and heat treatment process and / or mechanical appropriate to conduct a mechanical design.

Discussion

Task: 1

The selection of materials and manufacturing processes can be approached from two different perspectives. The first focuses on the result of the selection process functionality only contribution to the project and all the innovation component supports the morphology, thus the material and process be responsible only physical support to the project. In this way a professional in the area of materials and manufacturing may carry out the selection, almost without knowing the intricate details of the project and obviously without contributing anything more than his expertise to the process.

The second perspective is based on the possibility to generate radical or incremental innovation from one of the following: using a material or manufacturing process “new” (not used) in a application (shape and / or function) and scanned or use a material or manufacturing process not used in a application unexplored. Both strategies require designer a direct and purposeful in the selection process to the extent that they involve both physical and metaphysical issues project, that is, it addresses the material and process manufacturing as more than just hardware and explores sensory conditions thereof (Klocke & Kuchle, 2009).

Task: 2

This scheme is proposed methodology for selecting a material and a manufacturing process, formed from the need of the designer to be fully aware of what your design needs. In this way sequential has the definition of the functional requirements the project as a first step. The organization hierarchy and discrimination requirements are proposed as the next step. Then, you can determine the ideal profiles of both the material and the translating morphology attributes requirements and properties. Finally, we define what methods selection use and develops implications analysis end to determine the adjustments to be made or ideal profiles to the extent needed to compare with real profiles found. The definition of design requirements from the functional is taken as stated, as a starting point the process of selection of materials and processes manufacturing.

The alloying elements most commonly added to steel are nickel, manganese, chromium, molybdenum, vanadium, tungsten, cobalt, silicon and copper. An element, metallic or not, which is added to a metal (called the base metal) in such ...
