④ Creep refers to the phenomenon of slow plastic deformation as time continues to increase when the material is subjected to a stress far below the yield strength when the temperature is higher than the melting point of 0.5T. A typical creep curve is shown in Figure 2. According to the change of the deformation rate with time, the creep curve can be divided into three stages. Phase, which is the deceleration phase of creep. As time increases, the amount of deformation increases, and the rate of deformation decreases, see section AB in the right figure. The second stage is the constant creep stage. At this time, the creep deformation rate remains unchanged with the extension of the loading time, such as the BC section. The third stage is the accelerated stage of creep. The creep rate increases significantly. When the point D in the figure is reached, the material breaks. The higher the temperature, the greater the bearing force and the shorter the creep rupture time. Figure 2 Typical creep curve

Short comment on the main chemical components of NS322:

Nickel is one of the main components, which can improve the strength and toughness of steel and improve hardenability. When the content is high, it can significantly change some physical properties of steel and alloy, and improve the corrosion resistance of steel.

Chromium is also one of the main components, which can improve the hardenability and wear resistance of steel, and can improve the corrosion resistance and oxidation resistance of steel.

Copper is one of the auxiliary alloys, and its prominent role is to improve the atmospheric corrosion resistance of ordinary low-alloy steel, especially when it is used in conjunction with phosphorus. The Monel system is essentially a nickel-copper alloy.

④Molybdenum, as one of the auxiliary alloys, can significantly improve the hardenability and thermal strength of steel, prevent temper brittleness, and improve remanence and coercivity. Hastelloy is essentially a nickel-molybdenum alloy.

NS322 material heat treatment method and characteristics:

①Solid solution strengthening is an important form of metal strengthening, a phenomenon in which the strength and hardness of metals are increased by forming a solid solution. When the solute content is appropriate, the strength and hardness of the material can be significantly improved, while the plasticity and toughness are not significantly reduced, which is its characteristic.

②Aging enhancement is divided into artificial aging and natural aging. Natural aging strengthening is to strengthen the alloy during room temperature storage; while artificial aging strengthening is to strengthen the alloy during low temperature heating. Both are based on the premise of solid solution strengthening and both are to improve the strength of the alloy.

③ Precipitation strengthening is based on aging strengthening, and the purpose is to strengthen the alloy. The addition of cobalt, tungsten, molybdenum and other elements makes the alloy obtain a high yield strength.

④ Grain boundary strengthening occurs because the grain boundary of the alloy is a weak link at high temperatures. Adding trace amounts of boron, zirconium and rare earth elements can improve the grain boundary strength.

⑤ Annealing: the annealed state is the basic state of the furnace. The essence is to transform high-speed steel from austenite to pearlite. The function is to reduce the surface hardness of high-speed steel, improve the plasticity, in order to facilitate cold deformation processing such as cutting; make the composition of the steel uniform, improve performance, and prepare for further heat treatment; eliminate stress to prevent deformation or cracking.
