Morphology and Mechanical Properties of Pearlite
Pearlite is a mechanical mixture of ferrite and cementite. According to the morphology of cementite, pearlite can be classified into lamellar pearlite and granular pearlite. Lamellar Pearlite Lamellar pearlite consists of alternating layers of ferrite and cementit...Read more -
Effect of Carbon Content on the Process Properties of Iron–Carbon Alloys
Machinability The machinability of metallic materials is a highly complex issue, generally evaluated from aspects such as allowable cutting speed, cutting force, and surface roughness. Factors including the material’s chemical composition, hardness, toughness, thermal co...Read more -
Hot Working of Metals
Hot Working and Cold Working of Metals Plastic deformation processing is a method of forming and modifying metals by applying pressure. However, when plastic deformation is performed at room temperature, work hardening occurs, which increases the resistance to def...Read more -
Long-Term High-Temperature and Endurance Performance Measurement of Cast Steel
The following two measurement methods are applicable to stainless steel castings, alloy steel castings, and carbon steel castings. Endurance performance test The endurance performance test is to determine the strength of a material that does not break at a given temperat...Read more -
Investment Casting
Investment casting is a process in which several layers of refractory coatings are applied to the surface of a wax pattern. After hardening and drying, the wax pattern is melted and removed by heating, forming a mold shell with a cavity corresponding to the shape of the ...Read more -
Key Process Elements of Steel Casting Heat Treatment
The as-cast microstructure of steel castings depends on their chemical composition and solidification and crystallization processes. These typically exhibit severe dendritic segregation, extremely uneven microstructure, coarse grains, and a Widmanstätten (or reticular) s...Read more -
Impact Testing of Steel Castings
Impact testing is applicable to castings of various materials, such as stainless steel castings, alloy steel castings, and carbon steel castings. Impact testing is a dynamic mechanical test in which a notched specimen of a specific shape is pulled, twisted, or bent to ra...Read more -
Penetrant Testing of Steel Castings
Penetrant testing is applicable to stainless steel castings, alloy steel castings, carbon steel castings and other steel castings. 1. Basic Principles This is a detection method that uses the good penetration and capillary action of colored penetrants or fluorescent pene...Read more -
Heat Treatment of Corrosion-Resistant Stainless Steel Castings
1. Heat Treatment of Martensitic Corrosion-Resistant Stainless Steel Castings Martensitic corrosion-resistant stainless steel cast steel contains 13% chromium by mass and a high carbon content, resulting in excellent hardenability. After proper heat treatment, it exhibi...Read more -
Heat Treatment of Wear-Resistant Steel Castings
1. Solution Heat Treatment of Wear-Resistant High-Manganese Steel Castings – Water Toughening Wear-resistant high-manganese steel has a large amount of precipitated carbides in its as-cast structure, resulting in low toughness and prone to fracture during use. The primar...Read more -
Repair of Casting Defects
stings with defects are not necessarily scrap. With necessary repairs to remove the defects, as long as the technical requirements of the casting can be met, most repaired castings can still be used as finished products. The purpose of repairing casting defects is to avo...Read more -
Heat Treatment of Carbon Steel Castings and Medium- and Low-Alloy Steel Castings
Heat Treatment of Carbon Steel Castings Common heat treatment methods for carbon steel castings include annealing, normalizing, or normalizing + tempering. Normalized cast steel exhibits slightly higher mechanical properties than annealed steel. Due to the greater degree...Read more
