Accm

(english) In hypereutectoid steel, the temperature at which cementite goes into complete solution with austenite.

Braze Welding

(english) A family of welding procedures where metals are joined by filler metal that has a melting temperature below the solidus of the parent metal, but above 840 (450 C).

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.

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.

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

Box Annealing 2

(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.
