锻造(Forging)，是金属压力加工方法之一。指利用压力改变金属原料形状，以获得具有一定机械性能、一定形状和尺寸的锻件的一种加工工艺。

根据加工时工件的温度，可将锻造分为：热锻（再结晶（recrystallization）温度以上）；温锻（再结晶温度～再结晶温度的30%）；冷锻（再结晶温度的30%以下，一般是室温）。

通常把坯料加热后，用手锤、锻锤或压力机等锤击或加压，使它发生塑性变形，成为一定形状和尺寸的工件，所得的工件称为锻件，锻造能改变金属组织、提高其机械性能，因此在机械制造中常用来制造承受较大动载荷的零件。

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons. Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry.
