TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Hounsfeild Tensometer Torsion Tensile Tester Vickers Hardness Tester. Summery introduction This project will go into depth of the usage of material selection. After being paired with a fellow student we were given the task of testing 0.1% Carbon Steel‚ 0.4% heat treated steel along with a unknown specimen. To test these materials I will be using 4 types of methods Visual Inspection Hounsfeild Tensometer Torsion Tensile Tester Vickers Hardness Tester. Visual test While

Composite materials A composite material consists of two or more physically and/or chemically distinct‚ suitably arranged or distributed phases‚ with an interface separating them. It has characteristics that are not depicted by any of the components in isolation Most commonly‚ composite materials have a bulk phase‚ which is continuous‚ called the matrix‚ and one dispersed‚ non-continuous‚ phase called the reinforcement‚ which is usually harder and stronger. The arrangement of the fiber in the matrix

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two

Material deprivation (by which we mean the extent to which people have or are denied certain material things in life - which includes things like your level of income‚ standard of housing‚ access to consumer goods and so forth) is frequently cited as one of - if not the - main cause of differential educational achievement. Although the theory has gone in and out of political (and sociological) fashion over the past 50 or so years‚ most of the research in this area does suggest that there is some
