Today, let ’s talk about the factors that affect the speed of austenite modification.
1. The influence of heating temperature: With the increase of heating temperature, the nucleation speed, growth rate and atom dispersion of austenite can be added, and the composition speed of austenite is added.
2. The effect of heating speed: With the addition of the heating rate of the intermediate frequency induction heating equipment, each stage of the austenite composition process moves to a higher temperature scale. The faster the heating rate, the greater the degree of overheating of pearlite, and the shorter the modification latency. , The shorter the time required for conversion.
3, the influence of the chemical composition of steel
1. The effect of carbon content in steel: When the carbon content in steel is added, the total interface of ferrite and cementite is added, and the carbon can only be added. Together, the higher the carbon concentration in austenite, the faster the rate of atomic scatter and the greater the probability of austenite nucleation.
2. The effect of alloying elements on steel: The alloying elements in steel will not change the general process of austenitic steel during heating, but the alloying elements will nucleate and grow austenite, dissolve carbides, and homogenize austenite. have a great impact.
3. The influence of the original structure of the steel: The finer the original structure of the steel, the larger the dispersion of carbides, the smaller the distance between ferrite and cementite, the more the phase interface, and the faster the austenite composition.
