An important step.For example, size, volume fraction, pattern and space point of the heat treatment to nickel base superalloy precipitation strength phase γ '
Cloth plays a decisive role.Therefore, develop the fast method of influence of the heat treating regime to structure and performance to determine optimal heat
Treatment process parameter has great importance to microstructure, the ideal mechanical property of acquisition of optimization material.
End quenching gradient heat treatment technics originates from jominy end quenching method [1] in 1938, and this method utilizes high temperature
The characteristics of cooling velocity changes with coupon change in location when sample end quenching forms gradient cooling rate inside a sample,
Corresponding tissue and performance also occur to change accordingly.End quenching method is used primarily for the research of H steel hardenability, and forms ASTM
Standard [2].
Then, Ben Ammar [3] etc. utilizes thermocouple assay sample quenching process by carrying out end quenching test to zircaloy
In temperature change successfully have recorded the cooling rate range that end quenching test is realized, obtain and by numerical simulation analysis
Cooling rate distribution.Newkirk, Ghrib [4-5] etc. carry out end quenching test to different-alloy respectively, have also all got pre-
End quenching test is extended to other alloy systems by the effect of phase, it was confirmed that end quenching experimental method can be used as a kind of pervasive heat treatment
Technique study material cooling rate-tissue-performance coherence.WANG [6] etc. develops the program of finite element of end quenching simulation, research
The thermo parameters method of sample during S50C steel end quenching, lays a good foundation for the temperature field simulation of entire steel end-quenched.
For the alloy of many engineering, heat treatment process parameter-tissue-performance database abundant is had been set up.
But the heat treatment process for developing a kind of novel alloy usually requires to spend high cost.Wherein, cooling rate is used as at heat
One of most important technological parameter in reason directly affects size distribution, volume fraction and the shape characteristic of precipitation strength phase, in turn
Influence the mechanical property of material.For a long time, it explores influence of the cooling rate to material structure and performance and generally relies on limited kinds
Cooling medium (such as water, oil, gas), it is difficult to establish huge cooling rate-tissue-performance coherence database.
In view of this, developed the continuous coo1ing gradient device based on induction heating early period, induction heating can quickly by
Sample is heated to target temperature section, but the thermo parameters method of entire sample is uneven, causes sample after end quenching heat treatment
Microstructure it is uneven, influence the accuracy and repeatability of subsequent experimental result.In addition, early-stage study uses resistance heating
Coupon is heated to target temperature by furnace, overcomes the non-uniform drawback in specimen temperature field, but sample is transferred to end quenching from resistance furnace
Transfer time in equipment is uncontrollable, influences experimental precision.
