The loss is basically because of the welding heat effect, the pre-tensile deformation and ageing.( 1 )Among the total loss, pre-tensile deformation caused the largest amount loss, approximately 50%.( 2 )The loss caused by welding heat effect is closely related to the heat input. Both too high or too low cause loss. There is a optimum heat input that causes the least loss? 熔合线在变形时效以后韧性要发生很大折损,韧性主要折损在以下几方面:焊接热影响;预拉伸变形;人工时效等。 (1)在各项折损中以预拉伸变形折损最大,约占总折损的50％左右。 (2)焊接热折损与焊接线能量有密切关系。焊接线能量太大、太小都会使热折损增大。在最佳线能量时热折损最小。 (3)总折损与线能量的关系与热折损和线能量的关系非常相似。也有一个最佳线能量。 (4)确定最佳焊接线能量是提高时效韧性的重要途径。合理地确定预拉伸变形量才能合理的利用材料。应根据结构的实际情况,正确的规定预拉神变形量。 熔合线在变形时效以后韧性要发生很大折损,韧性主要折损在以下几方面:焊接热影响;预拉伸变形;人工时效等。 (1)在各项折损中以预拉伸变形折损最大,约占总折损的50％左右。 (2)焊接热折损与焊接线能量有密切关系。焊接线能量太大、太小都会使热折损增大。在最佳线能量时热折损最小。 The high temperature corrosion resistance of steel was improved with a Fe-Al intermetallic coating applied to Steel-45 by light beam alloying. The effect of alloying processing parameters (the preplaced powder mass, m , and the heat input, q ) on the chemical composition, microstructure and phases of the alloying coatings was investigated by scanning electron microscopy, energy dispersive X-ray analysis, and X-ray diffraction.为了改善钢铁材料的耐高温腐蚀性能,用光束合金化方法在45钢表面合成了Fe-Al金属间化合物涂层。采用扫描电子显微镜、能量弥散X射线分析和X射线衍射研究了光束合金化工艺参数(粉末预置量
