Summary
The following paper "Engineering Materials" casts light on the materials used in engineering. As the author puts it, in a stress-strain curve, the proportional limit refers to the limit in which below, the material shows the expected direct relation between stress and strain (Hooke’s law). …

In this region, the material can regain its original shape after the removal of the loading or rather the stress. At this juncture, the material obeys Hooke’s law and the stress and strain relate proportionally, and the constant of proportionality is the modulus of elasticity. The structure of the particles is not altered which explains the reason the material regains its original shape after the removal of the stress.
It is the region just after the elastic limit. It is characterized by the graph flattening indicating destroyed proportionality between the stress and strain. Plastic deformations creep in, and the material loses the ability to regain fully its shape and size after the stress has been released. It takes place due to the rearrangement of the molecular or atomic structure that allows for the new shape and size.
Found just after the yielding region. It is characterized by a slight rise of the curve to the ultimate stress point. The behavior is due to the strength of the deformed atoms or molecules having a slight ability to withstand more stress up to the point beyond which complete deformation takes place. The rise of the curve in this region is what is termed as strain hardening.
It is the region beyond the ultimate stress point. In this region, a further increase of the stress leads to a reduction of the cross section of the material only in some parts and not the entire material. The constrictions formed are what is referred to as necking. It is the continuous reduction of the cross-section area that leads to the breakage and thus separation of the material.
Metallic materials are ductile thus has the ability to deform plastically up to some extent. On the graph, it is represented by the region beyond the proportional limit where the elastic limit has been exceeded. A force beyond the elastic limit affects the mobility of the atoms and dislocations thus the inability to regain the original shape after the force has been removed. ...Download file to see next pagesRead More

Engineering Materials Characterization of PM Stainless Steels

...? <Engineering Materials Characterization of PM Stainless Steels> and Section # of Powder metallurgy is a forming and fabrication technique to produce metal alloys. There are two main techniques to form and consolidate the powder, one being sintering and the other known as metal injection molding. In the experiment conducted two mixture were used to produce stainless steel. The one this report has special emphasis in the one with boron added to the powder mixture. Over the course of the report, certain aspects of boron and its effectiveness as a alloy element in ferrous mixtures will be discussed. Also the effect of temperature and the hardness effect on the steel produced from the mixture will be described with essential research material... read over the course of the experiment ad its description...

...?Engineering Materials Q1. It is the brittle feature that holds together the atoms of a material. As reported in Standard (2005), it has been proved that ceramics are made up of either covalent or ionic bonds; sometime both these bonds are seen in ceramics. Covalent bonds are directional and it will try very hard to resist deformation when a force is applied. The ionic bonding between the metal and non-metal components of the ceramics also makes material brittle. Generally, metals are tough since its atoms are tightly bonded by a sea of electrons which are valence electrons that wander around the substance and never stick with a single atom. As a result, the negative...

...August 10, 2009 Physical Metallurgy of Engineering Materials Answer Sheets Annealing is the heat treatment wherein a material is ed to heat causing changes in properties in strength and hardness the process is used to soften certain materials, refine the structure, thus making it homogeneous, and improve the properties of cold working. In some cases, like copper, steel and brass, the process is performed by the substantial heating of the material(until glowing) and allowing it to cool slowly. Nornalizing is an annealing process by which a metal is cooled in air after heating. This process is used to refine grains that have been deformed through...

Let us take an example of electrical cable. What is the foremost requirement on the material for this application? The material should have high electrical conductivity and which class of materials has high electrical conductivity- metals naturally; therefore, metals are the natural choices and there is no point wasting time in searching materials from the other classes of materials. Q2. Yield strength corresponds to the load at which plastic...

Engineering Materials to be used for Barbecues and Laptop Casing

...Engineering Materials to be used for Barbecues and Laptop Casing Barbecue is a method and apparatus used for cooking poultry, fish, and occasionally meat using the hot coals of charcoal, smoking wood, compressed wood pellets, and hot smoke of a fire (John, K, 2011). Typically, grilling means the act of cooking in this manner but quickly. Barbecue, on the other hand, is a much slower method that utilizes less heat compared to grilling. It is attended to for over a period extending for several hours. This assignment entails finding a range of engineering materials that could be used for the main body of the barbecues alongside the procedure used, finding a range of...

Notion of Engineering Materials

...Engineering Materials Task 1: Changes in properties and behaviour of metals Recrystallization refers to the process in metals that is achieved through heating whereby new sets of grains nucleate and grow to the extent of entirely consuming the original deformed grains (JOHN, 1991). Recrystallization has various effects on different metals as discussed below: In steel, recrystallization results to an increased tensile strength as well as ductility as the annealing temperatures increases. On the other hand, quality casts are produced from Aluminium at the temperature range of between 700oC to 750oC. Cold working usually affects the following properties in metals: tensile strength, ductility, hardness and...
