| Abstract: |
| Cracks were found with batches on the barrels of a certain type of rifle during its producing process, in order to find out the reason and control the quality, the lengthways impenetrated cracks of barrels from three different smelting lots were analyzed via metallograph and SEM. The result indicates that the cracks are caused by hydrogen embrittlements and the non-metallic inclusions. Some improvements were put forward for the process. |
