- Carbon Migration in Dissimilar Welded Joint
抄録
The present study was carried out to make clear the C migration in dissimilar metal welded joint at high temperature. To prepare test pieces, C steel and 2 1/4 Cr-1 Mo steel plates were welded with eight kinds of ferritic electrodes, 1/2 Mo, Cr-Mo Cr-Mo-V etc. and eight kinds of ferritic steel plates were welded with two kinds of sustenitic electrodes and 2 1/4 Cr-1 Mo steel was welded with Inconel electrode. These dissimilar welded joint specimens were heated at 500-800°C for 1-3, 000 h and then observed microscopically. The results are summerized as follows :<BR>(1) C in lower Cr steel migrated to higher Cr steel and carbides precipitated in higher Cr steel along fusion line. At higher temperatures, the ferrite grains coarsened in decarburized zone.<BR>(2) C migration was promoted with increase of Cr content in higher Cr steel and addition of V.<BR>(3) C migration was reduced with increase of Cr content in lower Cr steel and addition of V.<BR>(4) In the welded joints of Cr-Mo weld metals to C steel, the width of carbides precipitated zone increased with increase of Cr content in Cr-Mo weld metals up to 3 Cr-1 Mo steel and decrease with the increass of Cr content more than 3 Cr-1 Mo steel. The distribution density of carbides increased with the increase of Cr content in Cr-Mo weld metals.<BR>(5) The extent of C migration with 25 Cr-20 Ni weld metal was slightly more than 16 Cr-8 Ni-2 Mo weld metal. The extent of C migration with Inconel weld metal was less than those with 16 Cr-8 Ni-2 Mo and 25 Cr-20 Ni weld metals.
