In the first report, the age-hardening phenomena of Timken 16-25-6, the heat-resisting alloy for gas turbine material was studied. The solution-treatment was determined at 1150℃ for 1 hour. In this report, the influence of solution-treatment temperature (1100℃∿1250℃) and time (30 minutes, 10hours) on hardness, grain-size, and high-temperature age-hardening phenomena was studied. In general, the higher the solution-treatment temperature and the longer the heat-time was the lower became the degree of hardness, the larger the grain-size, and the more serious the distribution of mixed grain. After the age-hardening at 800℃ for 50 hours, the result was nearly the same in every case, althongh there were differences in the condition of grain-size and mixed grain. Hence, the temperature and time of solution-treatment should not be discussed from the viewpoint of hardness after aging, but from the view-point of the grain size and mixed grain conditions. In this report, the solution-treatment seemed effective at 1100℃ and 1150℃ for 30 minutes to 1 hour, or at 1200℃ for 30 minutes approximately.
