Effects of Nb Content on Mechanical Properties of the High Phosphorus-bearing Weathering Steel AITranslate
Abstract AITranslate
Investigation was made of the effects of Nb content on microstructure, strength and impact toughness of the high phosphorus bearing weathering steel by microstructure analysis, tensile test and impact test. The results show that with the increase of Nb content, the microstructure of the high phosphorus-bearing weathering steel becomes more uniform with weaker band like distribution, yield strength and tensile strength are improved at first and tend to be stable, and longitudinal impact energy in creases at first and then decreases, while transverse impact energy is the opposite. The high phosphorus bearing weathering steel with 0. 042 % Nb has the microstructure of obviously weakened band-like distribu tion,with the smallest average grain size,the maximum yield strength, tensile strength and longitudinal impact energy,and the minimum transverse impact energy. The high phosphorus-bearing weathering steel containing 0. 090% Nb,with no obvious band-like distributed microstructure, has the same strength, the narrowed anisotropy of impact toughness,compared with the one containing 0. 042% Nb.
