Those new methods. enrich and develop the traditional methods of predicting the microstructure of weld metal by Schaeffler Diagram, and are more concise and practical.展开更多
On the base of the methods of predicting weld metal microstructures of pearlitic dissimilar steel welded joints using austenitic type filler materials by Schaeffler Diagram[1], the other new methods of predicting and ...On the base of the methods of predicting weld metal microstructures of pearlitic dissimilar steel welded joints using austenitic type filler materials by Schaeffler Diagram[1], the other new methods of predicting and expressing weld metal microstnictiires of two kinds of dissimilar steel welded joints (pearlite/pearlite and austenite/pearlite) using austenitic filler materials by Schaeffler Diagram are suggested. Those new methods resolve some difficult problems which the microstructure kinds in two heterogeneous mixture zones of weld metal neighbouring two kinds of welded base metals are difficult to be accurately ascertained and the fluctuations of weld metal microstnictiires across fusion line are difficult to be conveniently expressed according to the traditional predicting method. The new predicting methods are more concise and practical.展开更多
