ABSTRACT:
The intensive quenching (IQ) method is an innovative thermal process for hardening steel parts.  In contrast to conventional quenching in oil or polymer, the IQ process is an environmentally friendly process conducted in highly agitated plain water. One of the major benefits of the IQ technique is the development of high, beneficial residual compressive stresses in the part surface layer during quenching. The IQ process is interrupted at the computer-calculated time when residual surface compressive stresses reach their maximum value. Residual surface compressive stresses improve part performance characteristics (strength, fatigue and wear resistance, service life, etc.). The paper describes applications of the IQ process to a variety of tool products made of shock-resistance cold work AISI S5 steel, high-speed M2 steel, 52100 steel and others. The paper describes intensive quenching equipment used for IQ demonstration studies.
