- M -


Machineability -
The relative ease of machining (cutting or forming) a metal or alloy. May be related to a machineability index under specified standard conditions.
Macrograph -
A photographic reproduction of macrostructure.
Macrostructure -
The structure of polished and etched metals as revealed at a magnification not exceeding ten times.
MAF® -
An adjustable preload fastener for soft core and composite materials.
MagneGage® -
An instrument for measuring plating thicknesses. The magnetic responses of plated and unplated parts of the same type are compared to determine the plating thickness.
Major -
(diameter) - In thread geometry, the diameter of the cylinder that bounds the crests of external threads or the roots of internal threads.
Malleable -
A characteristic of materials which permits a high degree of plastic deformation without rupture.
Maraging Steels -
Special high strength martensitic alloys capable of being precipitation hardened. Examples are Vascomax 250, 300 and 350.
Martensite -
A phase of steel produced by transformation of austenite upon cooling. Martensite is the hardest of the transformation products of austenite and is tempered to desired strength and hardness levels.
MechaniLok™ -
Lightweight 95 KSI blind bolt with mechanical locking feature for primary structure. Manufactured by Monogram Aerospace Fastners.
Metallography -
The science dealing with the structure and constitution of metals and alloys.
Metallurgy -
The science and technology of metals. Infastener manufacture, the concern with the physical and mechanical properties of metals as affected by composition, mechanical working, heat treatment and environment.
Micro Segregation -
Inmetallurgy, segregation within a grain or crystal.
Micrograph -
A graphic reproduction of microstructure. If produced photographically, it is called a photomicrograph, not a microphotograph.
Microstructure -
The grain structure of metals as exposed when a sectioned specimen is polished and usually etched and viewed at a magnification greater than ten times.
Minor -
(diameter) - Inthread geometry, the diameter of the cylinder that bounds the crests of internal threads or the roots of external threads.
Misalignment -
Lack of concentricity. Used in fastener applications to describe hole patterns which do not exactly match in members to be joined.
