Cemented carbide forging die is also called forging die. It has good heat resistance and fatigue resistance. It applies a certain pressing force through the closing and closing of the upper and lower dies, so that the forgings have better structure and mechanical properties.
The investment casting process is to use a fusible material to make a fusible model, apply several layers of special refractory coatings on it, dry and harden to form an integral shell, and then use steam or hot water to melt from the shell.
Isotopes are different nuclides of the same element. Their nuclides have the same number of protons but different numbers of neutrons. In nature, naturally occurring isotopes are called natural isotopes, and synthetic isotopes are called artificial isotopes.
The largest consumption of molybdenum in the steel industry is mainly used to produce alloy steel, stainless steel, tool steel and high-speed steel, cast iron and Roller. Most of the molybdenum is directly used in steelmaking or cast iron after industrial molybdenum briquetting, and a small part is first smelted into ferromolybdenum and then used in steelmaking.
Metal hardness is ability of a metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator of the hardness of a metal material. It can sensitively reflect the chemical composition, metallographic structure, Differences in heat treatment.
Recently, the research group of Fang Qianfeng, a researcher at the Institute of Solid State Physics, Chinese Academy of Sciences, made significant progress in the development of nanostructured tungsten-based alloys, and successfully prepared high-strength dual-nanostructured tungsten materials.
Vegetable oil is the most important food for the people. It is not only the most basic raw material for the food industry, but also an important raw material for industrial and agricultural production and national defense construction.
Sintering of tungsten-based heavy alloys is an important part. The sintering process has a great influence on the density, grain size, segregation and microstructure of the alloy.
