Abstract

The use of material that is specified as armor steel has a high resistant value. The quenching and tempering process is done to improve the toughness of the material. The process uses a temperature of 900oC on the quenching process with water medium and tempering temperatures of 125oC and 175oC holding time for 30 minutes. The tests include the impact test to determine the increase in the material and fractography to determine the ductility of the material.  There is a decrease in the value of the impact that occurs after the quenching process. The impact value is increasing due to the tampering impact of 32 J during the quenching process to 50 J. The fractography shows brittle fractures with ridges as a feature of brittle fractures. Rapid cooling rate processes in the quenching process cause cracks in the quenching specimens.

碳锰钢压力淬火参数及回火作用
使用指定为装甲钢的材料具有很高的耐受性。淬火回火工艺是为了提高材料的韧性。工艺采用温度为900℃的淬火工艺,以水为介质,回火温度为125℃,保温时间为175℃,保温时间为30分钟。试验包括冲击试验,以确定材料的增加和断口学,以确定材料的延展性。淬火过程后所发生的冲击值有所下降。由于淬火过程中32j的篡改冲击,冲击值增加到50j,断口形貌表现为脆性断口的脊状断口。淬火过程中的快速冷却过程会使淬火试样产生裂纹。
