冷轧薄板激光切割热影响区的深度及性能OA
Depth and performance of laser cutting heat affected zone of cold rolled sheet
为确定激光切割热影响区深度和激光切割热影响区对不同厚度、不同强度冷轧薄板产品力学性能的影响,通过改变激光切割速率的方法,对冷轧薄板产品进行激光切割试验,并对激光切割后热影响区的组织、深度和板材的拉伸性能进行研究.结果表明:热影响区可分为两部分,第一部分为激光切缝边缘的熔化区,第二部分为非熔化区,熔化区主要为马氏体,非熔化区主要为马氏体+贝氏体,激光切割速率越快,冷轧薄板的热影响区深度越小,冷轧薄板的强度越高或厚度越厚,热影响区深度越大;激光切割加…查看全部>>
In order to determine the depth of laser cutting heat affected zone and the influence of laser cutting heat affected zone on the mechanical properties of cold rolled sheet products with different thickness and strength,the laser cutting test of cold rolled sheet products was carried out by changing the laser cutting rate,and the microstructure,depth and tensile properties of the heat affected zone after laser cutting were studied.The results show that the he…查看全部>>
