A forging is an object in which metal is subjected to pressure and plastically deformed to create the required shape or appropriate compression force. This force is typically achieved through the use of a hammer or pressure. The casting process builds a refined grain structure and improves the metal's physical properties. In real life use of the component, a correct design will keep the particle flow in the direction of the main pressure.
Forgings need to be consistent from piece to piece, without any porosity, excess space, inclusions or other imperfections. This method produces components with a high strength to weight ratio. These elements are commonly used in aircraft structures.
The advantages of forgings include extendable length, retractable cross-section, retractable length, extendable cross-section, changeable length, and changeable cross-section. Shanxi Yongxinsheng Forging Co., Ltd., a major domestic forging manufacturer, produces various forgings, including crane forgings, wheel forgings, mining truck forgings, etc. The types of forgings include: free forging/hand forging, hot die forging/precision forging, upset forging, roll forging and die forging.
In today's era, people have higher requirements for the use of products, and accordingly they also have higher requirements for the forgings used to manufacture products. The manifestations of forging quality problems are many and complex. Certain types of forging defects will seriously reduce the performance of forgings, threaten the safety and reliability of use, and shorten the service life. The existence of such defects has serious consequences. of. Therefore, higher requirements are also put forward for the quality inspection of forgings, that is, forgings with defects must not be passed over, especially those with defects that seriously affect the performance. To achieve this, when inspecting and controlling the quality of forgings, in addition to fully using conventional testing methods and methods, we must also adopt faster and more accurate testing methods and methods that reflect the contemporary level, so as to make it more accurate. The assessment of forging quality, the judgment of the nature of forging defects, the judgment of causes and the analysis of the formation mechanism are more accurate and more realistic, so as to ensure that defective forgings are not missed and appropriate solutions can be taken to improve and enhance the quality of forgings.
As mentioned earlier, the inspection of forging quality is divided into appearance quality inspection and internal quality inspection. The inspection of appearance quality is generally a non-destructive inspection. It is usually inspected with the naked eye or a low-power magnifying glass. If necessary, non-destructive testing methods are also used. For internal quality inspections, due to the requirements of the inspection content, some must use destructive inspections, which are commonly referred to as anatomical tests, such as low-magnification inspection, fracture inspection, high-magnification tissue inspection, chemical composition analysis and mechanical property testing, etc. Some can also use non-destructive testing methods. In order to more accurately evaluate the quality of forgings, destructive testing methods and non-destructive testing methods should be combined with each other. In order to analyze the quality problems of forgings from a deep level, mechanical research work must also rely on transmission or scanning electron microscopes, electron probes, etc.
Usually, the inspection methods for the internal quality of forgings can be summarized as: macrostructure inspection method, microstructure inspection method, mechanical property inspection, chemical composition analysis method and non-destructive testing method.
The microstructure inspection rule is to use an optical microscope to examine the microstructure of forgings of various material grades. The items inspected generally include the intrinsic grain size, or the grain size at a specified temperature, that is, the actual grain size, non-metallic inclusions, microstructure such as decarburization layer, eutectic carbide unevenness, overheating, Burnt tissue and other required microstructure, etc.
The inspection of mechanical properties and process performance is to process forgings and test pieces that have undergone the specified final heat treatment into specified specimens, and then use tensile testing machines, impact testing machines, durability testing machines, fatigue testing machines, and hardness testers. and other instruments to measure mechanical properties and process performance values.
