The composition was optimized by tiny alloying, orthogonal test design and the hardness and impact toughness test for the different samples with different combination of alloy composition.
The comprehensive mechanical properties analysis mainly includes Cryogenic impacttest, Vickers hardness test, the Tensile testing at ambient temperature and the Bending test.
综合力学性能分析主要包括低温冲击试验、维氏硬度试验、室温拉伸试验和弯曲试验。
