| Abstract: | The effect to the mechanical feature of 60Si 2Mn vehicle block spring by adding B and rare earth is studied.The research result shows that the broken toughenss can be improved remarkably by the comprehensive action of minim B and RE,and the impact toughness,especially in low temperature can also be improved obviously with the comprehensive action.By the condition of this experimentation,the beneficial effect to the quenching of alloy is not obvious. |
