Ti-6Al-4V. Ti-6Al-4V (UNS designation R56400 ), also sometimes called TC4, Ti64, [ 1] or ASTM Grade 5, is an alpha-beta titanium alloy with a high specific strength and excellent corrosion resistance. It is one of the most commonly used titanium alloys and is applied in a wide range of applications where low density and excellent corrosion ...
Titanium alloys are generally classified into four main categories: [ 1] Alpha alloys which contain neutral alloying elements (such as tin) and/ or alpha stabilisers (such as aluminium or oxygen) only. These are not heat treatable. Examples include: [ 2] Ti-5Al-2Sn-ELI, Ti-8Al-1Mo-1V. Near-alpha alloys contain small amount of ductile beta-phase.
2024 aluminium alloy is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength-to-weight ratio, as well as good fatigue resistance. It is weldable only through friction welding, and has average machinability. Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn ...
The Unified Numbering System for Metals and Alloys ( UNS) is an alloy designation system widely accepted in North America. Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property. A UNS number alone does not constitute a full material ...
Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies. Technical standards exist to provide glossaries of ...
AMS counts the 14 C / 12 C ratio directly, instead of the activity of the sample, but measurements of activity and 14 C / 12 C ratio can be converted into each other exactly. [60] For some time, beta counting methods were more accurate than AMS, but AMS is now more accurate and has become the method of choice for radiocarbon measurements.
American Measurement Standard. The American Measurement Standard is an authoritative measurement standard for use with single-family dwellings. The AMS 2020 edition is a voluntary guide developed for the measurement, calculation, and communication of square footage in residential dwellings.
Aerospace bearing. US Airman cleans thrust bearings, an example of aerospace bearings. Aerospace bearings are the bearings installed in aircraft and aerospace systems including commercial, private, military, or space applications. Materials include M50 tool steel (AMS6491), carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C ...
