珠光体是奥氏体(奥氏体是碳溶解在γ－Fe中的间隙固溶体)发生共析转变所形成的铁素体与渗碳体的共析体。其形态为铁素体薄层和渗碳体薄层交替重叠的层状复相物，也称片状珠光体。
Pearlite is an eutectoid of ferrite and cementite, it is formed by a eutectoid reaction of austenite (austenite is an allotrope of iron or a solid solution of iron when carbon is dissolved in γ－Fe). Pearlite is a two-phased, lamellar or layered structure composed of alternating layers of ferrite and cementite, it is also called lamellar pearlite.

用符号P表示，含碳量为ωc＝0.77％。在珠光体中铁素体占88%,渗碳体占12%,由于铁素体的数量大大多于渗碳体,所以铁素体层片要比渗碳体厚得多.在球化退火条件下,珠光体中的渗碳休也可呈粒状,这样的珠光体称为粒状珠光体.
It is indicated by a P symbol, carbon content is ωc＝0.77％. The proportion of ferrite and cementite in pearlite is 88% and 12% respectively. As the ferrite content is much higher than cementite, its layers are much thicker than the cementite layers. Under the condition of spheroidizing annealing, the cementite can also appear in granular form, this type of pearlite is called granular pearlite.

问题补充：

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.

Pearlite is austenite (carbon austenite was dissolved in the crystallology gamma - Fe) GongXi transformation between ferrite and formed the cementite GongXi body. Its form is thin and ferrite thin alternating cementite overlapping layer complex phases, also called flake pearlite. Use symbols to ω, P c = 0.77% carbon. In ferrite pearlite for 88%, cementite 12%, because the Numbers of ferrite than cementite, so the ferrite nano-composite than cementite. In the thick of ball annealing of pearlitic condition, can also be a carburizing Hugh granular, such as the pearlitic granular pearlite.

Common heat annealing, is divided into fire, quenching and tempering.
Annealing is heated to a temperature of the steel scheled time, heat preservation with slow cooling (usually furnace cooling), close to balance the organization heat treatment process.
Is the fire is heated to YaGongXiGang or steel GongXi and GuoGongXiGang above 30-50 ° c, insulation appropriate time in static air cooling after heat treatment process.
The steel quenching is heated to YaGongXiGang or AC1 above 30-50 ° c, after cooling medium heat rapidly cooled heat treatment process.
Tempering is after quenching parts to AC1 heated to a temperature below, proper insulation, heat treatment process of cooling to room temperature.

Pearlite is the eutectoid by ferrite and cementite which are formed by eutectoid reaction of austenite (austenite is the interstitial solid solution which is carbon-dissolved in the γ-Fe). The morphology are composite material overlaped by layered thin ferrite and layered thin cementite, also known as flaky pearlite represented by Symbols P and the carbon content ωc = 0.77%. Pearlite contains 88% ferrite, 12% cementite, e to the number of ferrite is much more than cementite in pearlite, so the layer of ferrite is also much more thicker. Under the condition of the ball annealing, the cementite in pearlite can also present grainy, it is called granular pearlite pearlite.
查的辛苦，帮忙给点分吧。
