二、水火弯板对合金钢性能影响的规律性合金钢由于有合金元素的加入,将会增加钢材在高温急冷之下淬硬变脆的倾向性。因此,即使是水火弯板的创始国——日本,对于合金钢能否采用水火弯板一事也一直犹豫了十五年之久,不敢贸然使用,或者在使用时也极为保守。直到一九七二年这一新工艺在日本才正式推广使用。我国虽早在一九七六年就加以推广,但在研究和使用上都还不够成熟。现综合我国部分试验研究情况,对水火弯板在合金钢
Second, the water and fire on the regularity of the impact of the alloy steel alloy steel due to the addition of alloying elements, will increase the steel quenching harden brittle tendency under high temperature quenching. Therefore, even Japan, the founding country of the water and fire bending board, has hesitated to use steel and iron bending for alloy steel for fifteen years and has not dared to use it in a rash fashion or is extremely conservative in its use. It was not until 1972 that this new process was officially put to use in Japan. Although China started to promote it as early as 1976, it is not yet mature enough in terms of research and use. Is a synthesis of some of our experimental study on the water and fire bending in the alloy steel
