But for the TEC overmatching, the residual stress σ〓 in the weld center is also related with the strain hardening coefficient H W of the weld metal. The residual stress σ〓 in the weld center got to the yield strength σ〓 increases little when the H'w is lower and somewhat exceeds the σ〓 when the H'w is higher.
而高胀匹配时的焊缝中心纵向残余应力σ〓还与焊缝金属应变硬化指数H〓有关,H〓较低时,焊缝中心纵向残余应力σ〓在达到焊缝金属屈服强度σ〓后不再升高;H〓较高时,焊缝中心纵向残余应力σ〓可超过焊缝金属屈服强度σ〓。

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8~2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8~10 grade. The yield strength is reduced by 10~20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).
结果表明,Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋,但前者的生产成本较低;水压减小,钢筋强度降低,上冷床温度越高,强度越低,推荐5段水冷器全开,水压均为1.8~2.0MPa,Q235钢筋的上冷床温度应控制在650℃以下;钢筋典型的金相组织(Q235)表层为回火索氏体,过渡层为珠光体+铁素体且部分铁素体呈针状,心部为珠光体+铁素体,晶粒度8~10级;自然时效后屈服强度下降10~20MPa,用人工时效可以模拟自然时效,工艺是100℃×2h或200℃×1h。

The results show that, the coefficients of welded joints are both greater than 0.9, but the yield strength of weld joint filled with Al-Mg-Zr-Sc welding wire is greater 100 MPa than that of filled with Al-Mg-Zr welding wire. It indicates that the Al-Mg-Zr-Sc welding wire is the best alteration of filling materials to weld of Al-Mg-Sc alloy.
但采用Al-Mg-Zr-Sc合金焊丝为填充材料时,焊缝晶粒组织明显细化,熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力,焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa,显著提高了Al-Mg-Sc合金焊接构件的许用强度,因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。
