Notes:
In order to investigate the effects of probe geometric shape on cooling curves ofquenchants, the ISO Inconel 600 alloy probe and a flat probe (Dimension: 120 mm × 120 mm ×20mm, phase-transformation free CrNi-steel) were both adopted to measure the cooling curves of oil,water and aqueous polymer quenchant. By comparing and analyzing the cooling rate curvesmeasured by the two kinds of probes, it can be found that the shape of water and oil’s cooling ratecurves obtained using different probes are almost same. While those for the aqueous polymerquenchant are not, especially at the initial cooling phase. During the initial cooling phase the coolingrate measured by the flat probe fluctuates in a narrow range, whereas this phenomenon couldn’t beseen while using the ISO Inconel 600 alloy probe. The reason could be contributed to the geometricshape difference of the two kinds of probes and the property of inverse solubility of the aqueouspolymer quenchant. In order to illustrate the inverse solubility property of the aqueous polymerquenchants the probe geometric shape should be considered
