Box Annealing

(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.

Blue Brittleness

(english) Brittleness exhibited by some steels after being heated to some temperature within the range of 300 (degrees) to 650 (degrees) F, and more especially if the steel is worked at the elevated temperature. Killed steels are virtually free of this kind of brittleness.

Butcher Saw Steel

(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49.

Burning 2

(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.

tempering sand

(โรงหล่อ) ส่วนผสมของทรายหล่อโลหะซึ่งผสมกับน้ำ มีความเปียกชื้นพอสมควรพอที่จะใช้งานหล่อโลหะได้

Ac3

(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.

Ac1

(english) The temperature at which austenite begins to form on heating.

Aecm, Ae1, and Ae3

(english) Equilibrium transformation temperatures in steel.

wet bulb temperature

ปรอทวัดอุณหภูมิที่มีผ้าทำเป็นปลอก สวมกระเปาะปรอทไว้แล้วทำให้ผ้าเปียก เรียกว่าอุณหภูมิปรอทเปียก

Blue Annealing

(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

temperature differential

ผลต่างของอุณหภูมิ

Burning

(english) (1) Permanently damaging a metal or alloy by heating to cause either incipient melting or intergranular oxidation. (2) In grinding getting the work hot enough to cause discoloration or to change the microstructure by tempering or hardening.
