Burning 2

แปลว่า(english) Heating a metal beyond the temperature limits allowable for the desired heat treatment, or beyond the point where serious oxidation or other detrimental action begins.

Aging 2

แปลว่า(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.

Blowhole 2

แปลว่า(english) A cavity which was produced during the solidification of metal by evolved gas, which in failing to escape is held in pockets.

Bright Annealing 2

แปลว่า(english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired.

Acid Process 2

แปลว่า(english) A steel making method using an acid refractory-lined (usually silica) furnace. Neither sulfur or phosphorus is removed.

Blast Furnace 2

แปลว่า(english) A vertical shaft type smelting furnace in which an air blast is used, usually hot, for producing pih iron. The furnace is continuous in operation using iron ore, coke, and limestone as raw materials which are charged at the top while the molten iron and slag are collected at the bottom and are tapped out at intervals.

Brittle Fracture 2

แปลว่า(english) Fracture preceded by little or negligible plastic deformation.

Box Annealing 2

แปลว่า(english) A process of annealing a ferrous alloy in a closed metal container, with or without packing materials, in order to minimize the effects of oxidation. The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled.

Blue Brittleness 2

แปลว่า(english) Reduced ductility occurring as a result of strain aging, when certain ferrous alloys are worked between 300 and 700 (degrees) F. This phenomenon may be observed at the working temperature or subsequently at lower temperatures.

Basic Oxygen Process 2

แปลว่า(english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel.
