The results show that martensite at transition area and the thermal stress in the joint of different material will cause crack in clad steel plate during welding.
结果表明,过渡区马氏体组织的生成,异种钢接头的热应力是产生焊接裂纹的主要原因。

The cure behavior, thermal stability and glass transition behavior of epoxy asphalts were investigated by using differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA).
The catalogue of transition-metals, thickness and the thermal expansion coefficient which influence the strength of the bonded places are studied as well.
