普通热处理分为退火、正火、淬火和回火。
退火是将钢加热到预定温度，保温一定时间后缓慢冷却（通常随炉冷却），获得接近于平衡组织的热处理工艺。
正火是将钢加热到亚共析钢或共析和过共析钢以上30-50℃，保温适当时间后在静止空气中冷却的热处理工艺。
淬火是将钢加热到亚共析钢或AC1以上30-50℃，经过保温后在冷却介质中迅速冷却的热处理工艺。
回火是把经过淬火的零件重新加热到低于AC1的某一温度，适当保温后，冷却到室温的热处理工艺。

普通热处理分为退火、正火、淬火和回火。
The types of ordinary heat treatment of steel are annealing, normalizing, quenching and tempering.

退火是将钢加热到预定温度，保温一定时间后缓慢冷却（通常随炉冷却），获得接近于平衡组织的热处理工艺。
Annealing is a treatment process of steel by heating to a predetermined temperature, holding for a certain time, and then cooling slowly to room temperature (normally together with the furnace), so that the equilibrium microstructure is obtained.

正火是将钢加热到亚共析钢或共析和过共析钢以上30-50℃，保温适当时间后在静止空气中冷却的热处理工艺。
Normalizing is a treatment process of steel by heating to 30-50℃ above temperature level of hypoeutectoid steel or eutectoid and hyper-eutectoid steel, holding for a suitable time and then cooling in still air.

淬火是将钢加热到亚共析钢或AC1以上30-50℃，经过保温后在冷却介质中迅速冷却的热处理工艺。
Quenching is a treatment process of steel by heating to 30-50℃ above temperature level of hypoeutectoid steel or Ac1 (正确写法是用小写c), it is then rapidly cooled in cooling agent after holding. (据我了解，淬火似乎不需要保温)。

回火是把经过淬火的零件重新加热到低于AC1的某一温度，适当保温后，冷却到室温的热处理工艺。
Tempering is a treatment process of steel by reheating the quenched components to a temperature below Ac1, after appropriate holding time, and then cooling to room temperature.

Answer 2

the ordinary thermal treatments are divided as annealing, normalizing, quenching and tempering.

Annealing is the thermal process to achieve updating equilibrium microstructure , which is heating the steel upto a predetermined temperature, holding for a certain time and cooling slowly.

normalizing is the thermal process which is heating the steel as hypoeutectoid steel or saturated steel, and hypereutectoid steel up to 30-50℃, holding for a certain time and cooling naturally.;

quenching is the process which is heating the steel as hypoeutectoid steel or AC1 up to 30-50℃, and cooling quickly in the coolant after heat insulation.

tempering is the process which is heating the spare parts being quenched up to a certain temperature under the temperature for AC1, holding properly and then cooling down to room temperature .
