    Mechanical properties of metal castings and forgings

    company  2016-03-24

    Brief description
    Automotive and aerospace enterprises are constantly on the lookout for more durable and can withstand higher stress materials. This makes the material manufacturers face provide stronger, lighter material requirements. As for auto parts, engines, gear box, axle beam, axle, crank, landing gear, engine frame etc..
    detailed information
    The mechanical properties testing of metal casting and forging.
    Metal forgings are being pressured by the plastic deformation of shape required shape or a suitable compression force of the object. The typical power by using a hammer or pressure to achieve. The casting process of building fine grain structure, and improve the physical properties of metal. In the real parts used in a correct design can make the particle flow in the main stress direction. Forging needs each piece is consistent, without any extra space, porosity, inclusions and other defects. This method of production of components, strength and weight ratio have a high ratio of. These components are usually used in aircraft structure. Automotive and aerospace enterprises are constantly on the lookout for more durable and can withstand higher stress materials. This makes the material manufacturers face provide stronger, lighter material requirements. As for auto parts, engines, gear box, axle beam, axle, crank, landing gear, engine frame etc..
    to attack
    The metal material will fracture under high impact force. The impact force of impact test can not only test component tolerance, can thus determine the selected material is appropriate.
    Solution
    Full automatic testing machine for the determination of metal material properties at room temperature or low temperature impact resistance under dynamic load, so as to judge the nature of the materials under dynamic load. Equipment according to national standard GB/T3808-2002 the pendulum hammer impact testing machine "production and development, to meet the GB GB/T229-1994 the metal Charpy Notch Impact Test Method" of metal materials of impact test requirements. The control system adopts professional industrial computer control, touch screen operation and display test results, simple operation, high working efficiency. The test machine is full automatic taking pendulum, placed, impact, sampling, data recording and other functions, for a large number of impact testing laboratory of metallurgy, machinery manufacturing sector superiority.
    stretching
    From the billet to the final forming is a time consuming and Gao Chengmu's production process, casting process is a kind of economical and efficient method for processing complex shape parts. The casting method can directly produce the finished product or the semi-finished product, thereby reducing the required amount of processing to the greatest extent. Similar to castings, forgings are usually irregular in shape. In many cases, the interception of a standard specimen from a casting or forging does not represent the whole of the component. Therefore, it is necessary to test the entire casting or forging. Due to the different shapes and sizes, it is difficult to clamp these parts, the test usually requires a higher force.
    Solution
    In order to meet the test requirements of hot rolling, casting and forging, CMT5000 for metal tensile, compression, bending, shearing, peeling, tearing, and load analysis of static performance test with stress control and strain control and displacement control three control mode in the tested three ways can be set in accordance with the procedures in the process of smoothing switch can automatically determine the ReH, ReL, Rp0.2, Fm, Rt0.5, Rt0.6, Rt0.65, Rt0.7, Rm, E and other experimental parameters, and test and analysis of mechanical GB, ISO, DIN, according to ASTM, JIS and other international standards; all these can be equipped with test fixture Loading-Rack standard sample used and extensometer, to produce accurate results and modulus. When testing the complete components, the machine can be equipped with a custom fixture, a T type slot test bench or a special fixing device to fit the shape of the test part. Fully understand and determine the specific application, test conditions and material characteristics, to provide accurate fixture solutions to meet user needs.
