| 摘要 | We study the difference in the maximum stress on a cylinder surface sigma(max) using the measured surface heat transfer coefficient h(m) instead of its average value h(a) during quenching. In the quenching temperatures of 200, 300, 400, 500, 600 and 800 degrees C, the maximum surface stress sigma(mmax) calculated by h(m) is always smaller than sigma(amax) calculated by h(a), except in the case of 800 degrees C; while the time to reach sigma(max) calculated by h(m) (f(mmax)) is always earlier than that by h(a) (f(amax)). It is inconsistent with the traditional view that sigma(max) increases with increasing Biot number and the time to reach sigma(max) decreases with increasing Biot number. Other temperature-dependent properties also have a small effect on the trendof their mutualratios with quenching temperatures. Such a difference between the two maximum surface stresses is caused by the dramatic variation of h(m) with temperature, which needs to be considered in engineering analysis. |
