Materials and Processes Vocab Flashcards
Ductility
The quality of being pliable and flexible without breaking
Ferrous Metals
Metals that contain iron as a base, magnetic
Non-Ferrous Metals
Metal that does not contain iron as base
Ex. Aluminum, titanium, copper
Metals Hardness Identification
F - As Fabricated
O - Annealed
H - Strain Hardened
H1 - Strain Hardened only
H2 - Strain Hardened and Partially Annealed
H3 - Strain hardened and Stabilized
Titanium
Highly strength to weight ratio and highly resistant to corrosion
1000 Series
99% pure aluminum
Hot Working
A process in which a metal is shaped under pressure at a fairly high temperature
Monel Metals
Alloys with 68% nickel and 29% copper, with small amounts of iron, manganese and other elements
Quenching
The process of rapidly cooling a hot metal to lock the atoms in place, creating a very hard but brittle microstructure
Hardening
When a drop in temperature make a liquid become a solid in metals with high amounts of carbon
Case Hardening
Producing a hard, wear-resistant surface over a strong, tough but malleable core
Alclad Aluminum
A corrosion-resistant aluminium sheet formed from high-purity aluminium surface layers
Annealing
The process of reheating a material and allowing it to cool slowly in order to remove internal stresses and create a more malleable material
Extrusion process
The forcing of metal through an opening in a die, thus causing the metal to take the shape of the die opening
Forging
The process of forming a product by hammering or pressing
Female Packing
Casting
A process in which hot liquid metal is poured into a mold that contains a cutout of the desired finished shape
Cold Working/Hardening
Mechanical working performed at temperatures below the critical range resulting in a strain hardening of the metal
Composite Materials
A mixture of different materials or things
Gaskets
Stationary seals between two flat surfaces
Two Part Sealants
Compounds requiring separate packaging to prevent cure prior to application and are identified as the base sealing compound and the accelerator
One Part Sealant
Prepared by the manufacturer and are ready for application as packaged
U-Rings
A multipurpose seal that can be fitted either on a rod or a piston cylinder
Eddy Current
An NDT used for the detection surface and sub-surface flaws through electromagnetic conduction
Male Packing
