Oxygen exists as a trace impurity element in the superalloy in the form of solid solution and oxide inclusion. Figure 1 shows the Al2O3 inclusion in the nickel-based superalloy.The presence of oxygen in the solid solution state has basically no influence on the performance of the superalloy, whil...
Nickel-based welding material for antioxidant, corrosion resistance, resistance to radiation ability, and the advantages of good comprehensive performance, are often used to service conditions demanding, high security requirements of welding structure. 690 nickel-based alloy is used in nuclear we...
What is vacuum high pressure gas quenching
Vacuum high pressure gas quenching refers to the hardenability materials of working die steels, high speed steels and alloy steels, which are heated to the critical temperature Ac3 or Ac1 after being loaded into the chamber of the vacuum furnace to achie...
The main purpose of metal smelting is to provide high quality metal melts for ingots.Therefore, it is necessary to study and determine the common rules in the smelting process of various pure metals and their alloys, so as to provide theoretical basis for formulating reasonable smelting process.

Vacuum induction melting equipment produces ultra-clean ingots, which are further refined by electrode remelting.In general, before rolling or forging, it is melted by vacuum arc remelting (VAR) process, and then processed into final products such as engines, transmission devices and structural p...
CAE Simulation technology
Gas turbine castings have complex structure, poor sequential solidification performance, poor complementary shrinkage, easy to produce shrinkage cavity and porosity.However, gas turbine castings are prone to crack under high temperature and pressure due to some defects s...
Aeroengine is a powerful driving force for the development of cast superalloys, and the continuous improvement of the casting process is the strong backing for the development of high-temperature Taijin.
Vacuum melting technology. Vacuum melting can significantly reduce the impurities and gas con...
One of the topics of titanium alloy vacuum melting is to develop a new process to significantly eliminate the defects of various inclusion forms in the ingot and ensure the chemical composition uniformity of the ingot. Vacuum consumable arc melting is conventionally used, but the inclusion proble...
Die steel can be roughly divided into three types: cold-rolled die steel, hot-rolled die steel and plastic die steel for forging, stamping, cutting, die-casting and so on. Due to the different uses of various molds and complicated working conditions, the steel for molds should have high hardness,...
Tool steel oil qenching, carbon tool steel has a very short temperature range in the transition tendency, and the incubation time is very short and the hardenability is very poor. In order to avoid non-M transitions before the formation of martensite, an extremely high critical cooling rate is re...
