This study conducted a basic investigation to improve the solidification cracking susceptibility of carbon steel. BTR is one susceptibilities cracking, and it said that reduced when smaller. three commercial filler metals was evaluated by using Trans-Varestraint test. EPMA EDS analysis weld metal microstructure revealed two compounds. The white structure composed silicon, manganese, sulfur, bla...

The current work was carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials; the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steels 310. Of the two joints involved, this paper describes the choice of welding consumables for the...

In this study, the liquation cracking temperature range (LCTR) of over-aged 247LC superalloy repair welds was quantitatively evaluated using spot-Varestraint testing, especially for application in weld heat-affected zone (HAZ). The metallurgical mechanism susceptibility and variation LCTRs superalloys clarified by analyzing microstructural characteristics at surface, thermodynamic calculations....
