【Abstract】 In this paper,by using the orthogonal method of regression,we have established the mathematical model between hardening properties of transformation by laser and the technological parameters for medinm carbon construction steel,carbon tool steel and medium carbon construction alloy steel. The remarkable degree of regression function and the precision of hardened indication have been ana- lysed.The results show that thismethod is practical and precise within the experimental condition.It has the important guided effect on production practice.更多还原
