alloy bowl rubbed with stone
แปลว่าขันลงหิน
Bronze 2
แปลว่า(english) Primarily an alloy of copper and tin, but additionally, the name is used when referring to other alloys not containing tin, for example, aluminum bronze, manganese bronze, and beryllium bronze.
Bismuth
แปลว่า(english) Chemical symbol Bi. A soft, course cystalline heavy metal with a silvery white color and pinkish tinge; usually produced as a by-product of copper,leaad and other metals. Has a thermal conductivity lower than all other metals except mercury. Used as alloying agent but leading use is in pharmaceuticals.
Brown Sharp Gages
แปลว่า(english) A standard series of sizes refered to by numbers, in which the diameter of wire or thickness of sheet metal is generally produced and which is used in the manufacture of brass, bronze, copper, copper-base alloys and aluminum. These gage numbers have a definite relationship to each other. In this system, the decimal thickness is reduced by 50% every six gage numbers- while temper is expressed by the number of B&S gage numbers as cold reduced in thickness from previous annealing. For each B&S gage number in thickness reduction, where is assigned a hardness value of 1/4 hard.
Brittle Inter-metallic Layer
แปลว่า(english) An iron-zinc alloy layer formed between the steel substrate and the free zinc of galvanized coatings.
Brinell Hardness Testing
แปลว่า(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.
Banding
แปลว่า(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working.
Box Annealing
แปลว่า(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.
Black Annealing
แปลว่า(english) A process of box annealing or pot annealing ferrous alloy sheet, strip or wire after hot working and pickling.
Babbitt
แปลว่า(english) An antifriction metal alloy used for bearing inserts;made of tin,antimony,lead and copper.
