| Abstract: | The 45 steel heat-treatment samples were heat-treated with different quenching medium and dif- ferent soaking time. The hardness tests on these samples were done. Their metallographic structures were analyzed by the metallographic microscope. The results showed that the hardness reached the highest and the quenching effect was better when the quenching medium was water. The grain size was smaller when the soaking time was 10 min. The quenching degree was higher when the soaking time was 30 min. |
