伸长表面
rectifying surface
- 根据计算和经验，侧弯伸长率小，且焊缝表面经过加工，不受表面质量影响，所以试验结果更接近实际，更为准确。
On the basis of calcuiation and experience, through side-bending test, test piece's extensibility is relative small, and its weld surface after processed is unaffected by the piece's surface quality. - 对试样进行了硬度、拉伸强度、断裂伸长率、热老化等性能试验；对老化后的试样表面进行了SEM表征。
Hardness, tensile strength, breaking elongation ratio and aging property of samples were tested and surface of sample after aging was represented by SEM. - 试样表面镀锡使ADI的抗拉强度和伸长率下降，镀锡层不能有效防止ADI的水脆化。
Soldering on ADI surface decreased the ADI tensile strength and elongation, and solder coating could not prevent from water embrittlement.
