对喷粉处理的16Mn 钢进行了机械性能测试和电子探针,能谱分析,并与未经喷粉处理的同炉钢进行了比较,结果说明,经喷粉处理后氮含量虽有提高,但由于钢中氮化铝夹杂为氮化钙所替代,大颗粒夹杂减少,并造成夹杂变性,使喷粉钢(与未喷粉钢相比)的抗拉强度,屈服强度和延伸率均无变化,而抗时效性能、冲击值均有明显提高,各向异性也大大改善。在试验的氮含量范围内([N]=62~97ppm),氮含量对喷粉处理钢的脆性转折温度无影响。
The mechanical properties test, electron probe and energy spectrum analysis of the 16Mn steel sprayed by powder were compared with that of the same steel without powdering treatment. The results showed that although the nitrogen content increased after the dusting treatment, However, due to aluminum nitride inclusions in the steel replaced by calcium nitride, large inclusions reduced, and caused by mixed degeneration, so that the powder sprayed steel (compared with the non-sprayed steel) tensile strength, yield strength and elongation were Changes, and anti-aging performance, the impact value has improved significantly, anisotropy has also been greatly improved. In the range of nitrogen content ([N] = 62 ~ 97ppm), the nitrogen content has no effect on the brittle transition temperature of the powder-sprayed steel.
