dc.description.abstractThis study focused on using thermal cycle simulator to investigate the metallurgical modifications that occur during welding of austenitic stainless steel type 304L and duplex stainless steel alloy type 2205. Thermal cycle simulator is known as an effective method to simulate the HAZ in the welded samples. Hence, the temperatures that are applied through this method should not reach the melting temperatures of the welded material. Different peak temperatures, from 500 to 1100oC were applied on the samples. Although the whole heating and cooling process was relatively short and did not exceed 7 minutes, both alloys were subject to metallurgical changes such as carbide precipitation in austenitic alloy and ferrite : austenite ratio in duplex alloy. The amount of carbide precipitation increased for longer exposure at specific temperatures. The amount of ferrite contained in duplex alloys increased with increasing peak temperature. However, other phases did not appear noticeably within this period, 7 minutes, at the peak temperatures applied in this study.en
