Effect of some factors on characterization of as-cast Ni74Cr16Mo5Ti4 superalloy ingot

摘要：

Ni74Cr16Mo5Ti4 superalloy was investigated on the equipments with high confident and accurate level. The siphon casting obtained smooth-glossy ingots with light-white surface. The optimal chemical compositions of Ni74Cr16Mo5Ti4 superalloy are 73.43％Ni, 16.64％Cr, 5.94％Mo, 3.99％Ti, 0.40％Cu, 0.49％AI. The casting temperature at 1,385°C is optimal when optimal contents of molybdenum and titanium are 5.94％Mo and 3.99％Ti, respectively. The crystallization and microstructure of as-cast ingots are firmly influenced by the casting temperature of Ni74Cr16Mo5Ti4 superalloy. The hardness obtains optimality of 334 HV, when optimal contents of molybdenum and titanium are 6％Mo and 4.2％Ti, respectively.
