Mechanical Properties Of Metals Ceramics And Polymers
Basis are comparable to the metals and ceramics.
Mechanical properties of metals ceramics and polymers. The key difference between polymers and metals is that the polymers are lightweight materials compared to metals. In fact properties of ceramics and glass can be tailored to specific applications by modifying composition including creating composite materials with metals and polymers and by changing processing parameters. While some of the stress strain curves for polymers might look similar to ones for metals polymers are mechanically different than metals or ceramics. Metals are of varying types and the applications of metals in the structural and mechanical work are significantly extensive however on primary basis metals can be classified in to main groups i e.
A highly elastic polymer may stretch over 10 times the original length. Are ferrous and nonferrous metals. Terms in this set 8 metal properties properties. These are typical properties.
In general they are relatively. 7 22 callister rethwisch 5e. Majorly composed of al 2 o 3 aluminum ceramic is a dense ceramic material with excellent thermal and electrical resistance properties. Common objects that are made of ceramic materials.
Copper is a soft malleable and ductile metal with high thermal and electrical conductivity. It is also resistant to corrosion and permeable for microwaves. The classification of metallic materials is explained below. Mechanical properties of polymers.
Dense high electrical conductivity high to fair thermal conductivities. If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size we can observe that the metal ball is heavier than the plastic ball. Deform under stress leading to ductile fracture. In addition many of the polymers are extremely ductile and pliable i e plastic which means they are easily formed into complex shapes.
Therefore this property of the polymer is highly advantageous because we can replace metal with plastic. One of the most desired properties of metal alloys is the hardenability. Properties of materials are classified into seven. Density ductility hardness corrosion resistance hardness thermal conductivity electrical conductivity wear resistance.
