Shrinkage during solidification of molten steel
The Shrinkage of Steel during Solidification
Solidification of steel has caused problems since steelmaking began. Shrinkage, i.e. the reduction in volume that is often found in steel as it solidifies, can cause significant structural problems and lead to a weakness in the finished product. It is ......

Forging Technology: Typical Defects of Non-ferrous Alloy Forgings - Coarse Grain
Metallurgical Defects of Forgings and Heat Treatment Techniques
Forging is an ancient metal forming process, which utilizes the plastic deformation of metal to obtain forgings with improved mechanical properties and ideal microstructure. With the opening of automobile, aerospace and other high-en......
microcrack toughening
Microcrack toughening
Microcrack toughening is a process of introducing microcracks into materials in order to increase their strength and hardness. By controlling the size, orientation and number of microcracks, the material’s mechanical properties can be considerably enhanced. The microcracks ......
Metallographic diagram of 65Si2MnWA (1100℃×20min+450℃×2s water cooling)
Metallographic analysis of 65Si2MnWA(1100℃×20min+450℃×2s cooling)
Metallographic testing is a process of evaluating materials through microscopic analysis. This method of material evaluation is widely used because it is a cost-effective and fast way to observe the behavior of the material and......
Fracture Analysis of 35 Steel Fatigue Specimen
Fatigue Fracture Analysis of 35 Steel Samples
Introduction
Fatigue fracture analysis is an important type of engineering analysis used to determine the cause of failure of components due to fatigue. It is a necessary engineering task to make sure that the design of components, structures, and ma......

AISI 4130 Steel Microstructure
AISI 4130 steel is a low alloy steel that is often used in the manufacturing of components and structures. It is a chromium molybdenum steel, and is classified as an alloy steel due to the presence of additional alloying elements. AISI 4130 has a relatively low carb......
Metallographic diagram of 45 steel (alloy powder laser cladding on workpiece surface)
Introduction
The gold phase diagram of 45 steel (surface alloy powder laser melting workpiece) is an important graphical representation of the physical and chemical properties of steel and other metals. It shows the limits at which the metals solid and liquid states are stable. The gold phase dia......
Longitudinal ground dendrite stem (red) near the fracture, revealing secondary cracks propagating along the dendrite
Secondary cracking along the grain boundaries near the fracture surface has been observed in various materials including brittle ceramics, polymers, and metals. The mechanism of secondary cracking is largely attributed to the formation and propagation of microcracks initiated at the grain boundari......
