    Forging materials

    The forging material is carbon steel and alloy steel of various components, followed by aluminum, magnesium, copper, titanium and its alloy. Material has its original state bar, ingot, metal powder and liquid metal. The cross-sectional area of the metal in the cross-sectional area and the deformation of the forging ratio is called the. The correct choice of heating temperature forging ratio, reasonable and holding time, the reasonable initial forging temperature and deformation of the final forging temperature, deformation rate reasonably and to improve product quality, reduce the cost of a great relationship.
    The general small and medium-sized forging material as blank with round or square bar. Microstructure and mechanical properties of the bar, good uniformity, shape and dimension accuracy, good surface quality, convenient batch production. As long as the heating temperature and deformation conditions of reasonable control, no need of large forging deformation can forge good forging.
    The ingot is used only for large forgings. The ingot is cast structure, large columnar grains and the osteoporosis center. Therefore must through the large plastic deformation, the columnar grain crushing into fine grain, will loose compaction, in order to obtain metal microstructure and excellent mechanical properties.
    Powder metallurgy preform is pressed and sintered in the hot state, the flashless die forging can be made into powder forging. Forging powder close to the general die forgings density, good mechanical properties, and high accuracy, can reduce cutting follow-up. Powder forging internal microstructure, no segregation, can be used in the manufacture of small gear workpiece. But the price is much higher than the general powder bar price, the application in the production of limited. ,
    The static pressure in the liquid metal die casting, the solidification, under pressure, flow, crystal plastic deformation and forming die forgings, can obtain the required shape and properties. Liquid metal forging is formed between the die casting and forging of complex thin-walled parts, especially in general difficult to forming die.
    Forging materials in addition to the usual materials, such as carbon steel and alloy steel of various components, followed by aluminum, magnesium, copper, titanium and its alloy, high temperature alloy, nickel base superalloy, deformation of alloy of cobalt base superalloy by forging or rolling manner, but these alloys due to the plastic region a narrow, so the forging the difficulty will be relatively large, the heating temperature of different materials, open forging temperature and forging temperature has strict requirements.
