The effect of pre-heating and pre-cold treatment on the formation of liquation and solidification cracks of nickel-based superalloy welded by laser beam
The present study has evaluated the solidification and liquation cracks of GTD-111 superalloy by pulsed Nd:YAG laser techniques. For this purpose, samples were subjected to different temperatures under the conditions of heat treatment (1120, 1200 and, 1230 °C), pre-cooling (−30 and 0 °C), and pre-he...
