摘要：

Simplified thermal models in laser and electron beam surface hardening can be very useful to industrial users. Hardening depth as a function of austenitization temperature and Peclet number is evaluated for one-dimensional stationary and two-dimensional uniform strip moving heat source problems without melting. Reliable correlations for predicting both hardening depths and maximum temperatures are given in terms of dimensionless meaningful parameters. Calculated values are also compared with experimental results reported by other authors.
