Brittle Inter-metallic Layer

แปลว่า(english) An iron-zinc alloy layer formed between the steel substrate and the free zinc of galvanized coatings.

Broaching 2

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.

Blister 2

แปลว่า(english) A defect in metal, on or near the surface, resulting from the expansion of gas in a subsurface zone. Very small blisters are called pinheads or pepper blisters.

Burnishing 2

แปลว่า(english) Smoothing surfaces through friction between the material and material such as hardened metal media.

Burr 2

แปลว่า(english) Roughness left by a cutting operation such as slitting, shearing, blanking , etc.
