★ Ferrous Metals

 (irons, carbon steels, alloy steels, stainless steels,etc)

★ Non Ferrous Metals

(aluminum, copper, magnesium, nickel, titanium, precious metals, refractory metals, super alloys)

𝟐- 𝐂𝐞𝐫𝐚𝐦𝐢𝐜𝐬

★ Defined as “an inorganic, nonmetallic solid that is prepared from powdered materials, is fabricated into products through the application of heat, and displays such characteristic properties as hardness strength, low electrical conductivity and brittleness.

★ Such as aluminum and oxygen (alumina-Al2O3), calcium and oxygen (calcia - CaO), and silicon and nitrogen (silicon nitride-Si3N4).

★ Ceramics' Properties:

- Brittle in nature. Ceramics can also be formed to serve as electrically conductive materials or insulators.

- Some ceramics, like superconductors, also display magnetic properties. They are also more resistant to high temperatures.

★ Examples: glass, cements, ceramics, energy conversion, petroleum, and chemicals industries)

𝟑- 𝐏𝐨𝐥𝐲𝐦𝐞𝐫𝐬

★ As Thermoplastics plastics, Thermoset plastics, Elastomers

★ A polymeric solid is a material that contains many chemically bonded parts or units which are bonded together to form a solid.

★ Plastics are a large and varied group of synthetic materials which are processed by forming or molding into shape.

★ Elastomers or rubbers can be elastically deformed a large amount when a force is applied to them and can return to their original shape (or almost) when the force is released.

★ Polymers distinct properties:

- Less dense than metals or ceramics.

- Resist atmospheric and other forms of corrosion.

- Offer excellent resistance to electrical current.

𝟒- 𝐂𝐨𝐦𝐩𝐨𝐬𝐢𝐭𝐬:

★ As Grain Reinforced Epoxy (GRE) or Fiber Glasses or Concrete.

★ Defined as a combination of two or more distinct materials, each of which retains its own distinctive properties, to create a new material with properties that cannot be achieved by any of the components acting alone.

★ Fiberglass sheet is a composite since it is made of glass fibers embedded in a polymer.

★ Composite materials are said to have two phases. The reinforcing phase is the fibers sheets or particles that are embedded in the matrix phase.

★ The reinforcing material and the matrix material can be metal, ceramic, or polymer. Typically, reinforcing materials are strong with low densities while the matrix is usually a ductile or tough material.

Causes of Weld cracks:

Image
 Causes of Weld cracks: Use of hydrogen when welding ferrous metals. Residual stress caused by the solidification shrinkage. Base metal contamination. High welding speed but low current. No preheat before starting welding. Poor joint design. A high content of sulfur and carbon in the metal.

Magnetic Particle Testing (MPT)

Image
 Magnetic Particle Testing    Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection, i.e. a nondestructive examination (NDE) technique used to detect surface and  subsurface diecounitinuties  in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conducting magnetic particle test Is part of ASME SECTION V ARTICLE 7 requires the magnetic particle visible method (color contrast) be evaluated with a minimum light intensity of 100 footcandles on the part surface Advantages of the Magnetic Particle method of Non-Destructive Examination are: It is quick and relatively uncomplicated. It gives immediate indications of defects. It shows surface and near surface defects, and these are the most serious ones as they concentrate stresses. Magnetic Particle Testing (MT), also referred to as Magnetic Particl...
