. 8 0 . 1W e ld C 2 . 2 0 . 1Not a significant change in volume % to explain large difference in toughness. Vickers Hardness Measurement Observation Large scatter in hardness values along depth of the weld C but not in weld A. Why large scatter ? Aoffset offset distance 5 mm from weld centerline Reason for scatter in hardness.. Dilatometric measurements revealed the difference in Ac1, as expected. Though, difference in Ac1is less, it is enough to cause a change in temper effects of reheated zones in a multipass weld. Low Mn = High Ac1 High M。阅读剩余 0%
