Q315NS Karfe

An bincika tasirin tsarin zafin walda akan lalatawar electrochemical na Q315NS a cikin H2SO4 da maganin HCl. An yi amfani da kekuna daban-daban na zafi mai zafi daban-daban a cikin na'urar gwaji ta Gleeble thermal-force don kwaikwayon walda HAZ, kuma an aiwatar da ma'auni na electrochemical. Sakamakon ya nuna cewa an samar da ƙaramin tsari na granular bainite a cikin CGHAZ yayin da wasu sun ƙunshi ferrite da pearlite. Lantarki electrochemical na daban-daban HAZ ya bambanta a H2SO4 da HCl, saboda daban-daban microstructure. BM da HAZs a cikin 50 wt. % H2SO4 Magani yana da takamaiman hali na wucewa, yayin da babu halin wucewa a cikin 3.5 wt. % HCl mafita. Juriya na lalata a cikin HAZ sun yi ƙasa da na BM. Bugu da ƙari, juriya na lalata a cikin CGHAZ shine mafi rauni
